6 Incredible Ways Data Science Is Changing The Real Estate Sector

Formulating the Property Price Indices 

Investors make wise decisions using reliable data and insights gained through the data science process. As data technology develops, investors will be able to make decisions that are more profitable and will be able to predict the future value of the assets they invest in with great accuracy.

These decisions have generally been influenced by historical property values, the character of the community, and accessibility to highly prized neighborhood amenities like supermarkets, schools, and parks. However, accurate projections can still be challenging due to regional property changes, but data science makes this challenging.

As a result, big data can be used in data science methodologies to go beyond conventional data and provide each property's distinctive characteristics. By considering property attributes and demographics, among other things, it can create detailed sub-market indices. Additionally, in some postal districts, it can be used to predict property returns.

Reshaping the Marketing Strategy for Trend Prediction

Data science in real estate facilitates data gathering and evaluation from many sources. As a result, businesses can better understand consumer behavior and preferences, evaluate the competition, and creatively market their services.

Once the user's preferences have been identified, the target market can be attracted using virtual staging, 3D rendering and visualization, Google or Facebook adverts, and listings.

Additionally, it is crucial to pay attention to the real estate postings for social media marketing and keep the fundamental aesthetics of the posted content, given that an increasing number of individuals increasingly prefer to search for real estate listings online.

Thus, This allows purchasers to focus their real estate research on just a few possibilities they are actually interested in.

Properly Valuation

In the modern age, data-driven property valuation is a true deal-breaker. For instance, if someone wants to purchase a specific property, they might use an automated valuation model, which could resemble a simple website. This model will give them an accurate asset valuation in seconds. In addition, the programme can also show historical information about the property and forecast pricing in the future.

These algorithms for evaluating real estate are fed with real-time data. As a result, both buyers and real estate agents will always have access to relevant details.

Forecasting valuation

Investors, agents, and real estate buyers must be aware of the direction the property market is likely to take. Implementing scientific knowledge in this situation makes sense. Businesses can utilize predictive analytics to forecast the value of properties in a specific area. Companies can use predictive analytics to estimate the value of properties on a particular site. Real-time analysis of rental and purchase demand and real estate value trends is an excellent forecasting tool.

Cluster Analysis 

The real estate market is incredibly unstable. It differs not only within a certain nation but also within a particular city, town, or place. Pricing is affected by many variables, including macro- and microeconomic conditions and regional patterns. This is where cluster analysis can be helpful. These techniques enable uncovering these patterns within datasets. 

Real estate investors might find cluster analysis to be especially helpful. 

For instance, if an investor misses the opportunity to invest in a certain property, they can use cluster analysis to determine whether any other properties will perform similarly or otherwise.

Complex cycle analysis is produced with the help of cluster analysis, which also benefits the evaluation of macroeconomic factors throughout time. 

GIS (Geographic Information System)

As is obvious, location has always been a crucial component in the real estate sector. And the industry can benefit significantly from GIS tools, given the abundance of data readily available from numerous sources. 

A geographic information system is used to perform in-depth geospatial analysis, which is an essential component of data science. It enables the collection, analysis, and processing of information by leveraging and combining various data types, such as addresses, postal codes, geographic coordinates, etc.

After thoroughly analyzing the data, the system shows the user sophisticated mapping visualizations and unique insights. 

Additionally, GIS may give real estate firms details on the best locations for malls, retail stores, wetlands nearby, and other structures. 

To determine whether a property is worth investing in, real estate investors might seek data about it beforehand.

Final Thoughts! 

To conclude, the real estate industry has yet to embrace data in the way modern businesses are taking advantage of it. However, data science and analysis will significantly affect how agents and brokers operate. How we collect, analyze and manage information will be vital to making that 'big' sale. Thus, in the real estate industry, data science can improve decision-making and create a more efficient process.

5 NLP Techniques That Data Scientists Must Know

Natural language processing is an artificial intelligence subfield that aims to make machines understand natural languages in the same way humans do. The Turing Test (also known as the Imitation Game) was developed in the 1950s to determine whether a machine can be considered intelligent."

The Turing test is a watershed moment in artificial intelligence research and development. According to it, if a human cannot tell whether they are speaking to a machine or a person during a conversation, the Turing test has been passed, and ultimate machine intelligence has been achieved. Although scientists are still debating whether a machine has passed the Turing test, there are many exciting applications of NLP in business.

Gmail can autocomplete your mail as you type, LinkedIn can provide response recommendations to a text message, and Google's search engine auto-fills the search query for you and returns the most relevant results, not to mention the Virtual Assistants, Siri and Alexa, who can converse as naturally as a human. OpenAIs GPT-3, the most powerful and most significant artificial intelligence model trained on 45TB of data and processed through 175 billion parameters, can produce language that is both stunning and unsettling. 

Here are the top 5 NLP techniques, every data scientist must know:

Stop Words Removal

Stop word removal is the preprocessing procedure that follows stemming or lemmatization. Many words in any language are essentially fillers with no meaning linked to them. These are generally words that are used to connect sentences (conjunctions- "because," "and," "since") or to illustrate a word's relationship to other words (prepositions- "under," "above," "in," "at"). These words constitute most of the human language and are not particularly useful when constructing an NLP model. However, because it depends on the objective, stop word removal is not a traditional NLP approach to incorporate for every model. 

When doing text classification, for example, if the text needs to be classified into different categories (genre classification, spam filtering, auto tag generation), then removing stop words from the text is beneficial because the model can focus on words that define the meaning of the text in the dataset. For detailed explanation, refer to the IBM-accredited Data Science Course in Delhi, which is trending in the market. 

TF-IDF

A statistical method called TF-IDF is used to assess a word's significance within a group of documents. The TF-IDF statistical measure is computed by multiplying two distinct values: the term frequency and the inverse document frequency.

The idea behind TF-IDF is to find essential words in a document by looking for words frequently occurring in that document but not elsewhere in the corpus. These words could be computational, data, processor, etc., in a computer science document, but extraterrestrial, galactic, black hole, etc., in an astronomical document. Now, let's look at an example of the TF-IDF NLP technique using Python's Scikit-learn library.

Extraction of Keywords

When you read a piece of text, whether it's on your phone, a newspaper, or a book, you do this involuntary action of skimming through it- you generally skip filler words and pick significant terms from the text, and everything else fits in context. Keyword Extraction performs the same function as locating essential keywords in a document. Keyword Extraction is a text analysis NLP tool for quickly gaining valuable insights on a topic. Rather than going through the entire manuscript, the keyword extraction technique can be utilized to condense the content and extract relevant terms.

The keyword Extraction technique is beneficial in NLP applications where a company wants to identify customer problems based on reviews or if you're going to identify topics of interest from a recent news item.

Embeddings of Words

Given that machine learning and deep learning algorithms only accept numeric input, how can we turn a block of text into numbers that these models can use? When training any model on text data, whether classification or regression, it is necessary to convert it to a numerical representation. The straightforward solution is to use the word embedding approach to representing text data. Using this NLP method, you can express words with related meanings in a similar way.

Sentiment Analysis

The emotional analysis is another name for sentiment analysis. One of the essential NLP tools for text classification is AI, often known as opinion mining. The goal is to categorize text such as a tweet, news article, movie review, or any text on the internet into one of three categories: positive, negative, or neutral. Sentiment Analysis is most commonly used to reduce hate speech on social media platforms and identify distressed customers in negative reviews.

These were the 5 popular NLP techniques every budding data scientist should master. Furthermore, if you’re considering a career in data science and AI, take a look at the top Data Science Certification Course in Delhi. Enroll and explore the top ML techniques to gain a competitive edge.

How Data Science can Enhance SEO Tactic

Data science is one of the trendiest themes in modern digital marketing. It encourages data-driven business decision-making. In the opinion of two out of every three marketers, these decisions are preferable to their non-data-driven alternatives. Data science enhances digital marketing operations, making them speedier and more effective. The practice of SEO is one of these methods.

Best practices for SEO have frequently been based on conjecture. And it still does. It is however inexplicable that marketers wouldn't leverage the wealth of data to streamline their SEO activities given its availability. Data helps SEO by allowing marketers to evaluate the effectiveness of previous strategies.

How to improve your SEO by utilizing data science

Modern methods, tools, and techniques are used in data science to analyze vast amounts of data and get valuable information from it. Data is just a collection of statistics; science gives it meaning and enables organizations to make wise decisions. Data has become the valuable resource it is now thanks to data science.

Data science may help you make more data-driven decisions, which can improve your SEO.

The data-driven SEO strategies listed below can be used in your SEO campaign:

Enhance the user experience on the website

As previously said, Google's most recent adjustments showed a tendency for them to rank websites with good UX higher than those with poor UX.

The content is but one component of the overall website experience. Content helps to make a website more useful. Usability is essential if you want to improve your website's reputation among users and search engines. How simple it is for users to navigate through your website determines its usability. Consequently, it depends heavily on web design.

SEO competitor analysis

Competitor analysis entails gathering SEO information from the websites of your rivals and using that information to inform your own SEO approach.

When performing your own SEO, a thorough competitor study provides you with a leg up. You no longer need to put tactics into action based on assumptions and then optimize them. You may use the data of your competitors to find practical, tried-and-true strategies, put them into practice, and get going right away.

Finding your rivals is the first step in doing successful competition analysis. The next step is to do a thorough page and backlink analysis and finish your competitor research using tools like SEMrush and Ahrefs. Based on your study, create a competitor analysis report, and use this report to inform the development of your SEO strategy. With a Data science Course in Delhi, you can learn more about analytics techniques utilized in SEO. 

Link building for SEO with data

Another SEO tactic is link building, which tries to get high-quality backlinks from other websites with high domain authority. It aims to increase the authority of your website in the eyes of search engines. Backlinks are one of the most important ranking factors because, despite all the updates, Google still gives a lot of weight to the quality and quantity of backlinks a website has.

This data-driven backlinking strategy can help you build more links, which will improve your SEO performance. Mattress Review's CEO and founder, Trond Nyland, wanted to improve the SEO of his website. He used a backlinking strategy that was data-driven and discovered information about the websites that provided high-quality backlinking prospects.

In comparison to the eight backlinks he received from his non-data-driven backlinking strategy, he swiftly obtained 175 backlinks from high-potential websites using his data-driven method. We can quickly calculate that backlinking based on data was over 400% more accurate than backlinking without data. What further proof do you require to begin utilizing statistics to guide your backlinking strategy?

Metrics for tracking and improving user behavior

A link between user behavior measurements and rankings has been flatly refuted by Google executives. But everyone may agree that Google factors a website's user experience into its ranking. Therefore, in my opinion, user behavior measurements must be given some weight. How else could it evaluate page experience in the absence of that?

When evaluating a website's user experience (UX), search engines like Google may take into account a wide range of various factors. CTR, Dwell Time, Bounce Rate, Time On Site, Pages Per Visit, Repeat Visits, etc. are a few examples of these metrics. To find areas for improvement, monitor these metrics and compare them to industry benchmarks. Then, using the information from your audience analysis, optimize them for (possibly) higher search engine rankings.

Conclusion

There is no denying the advantages of data science for SEO. Drawing conclusions from information on customer behaviour and preferences can improve the user experience on the website. It can also jumpstart your SEO efforts by gleaning useful information from competitor analysis data and boosting the effectiveness of your link-building campaign. You should be aware, though, that the advantages of data science depend on the veracity of your data and the method you use to analyze it. To learn more about data science and its tools, sign up for the Data Science Certification course in Delhi, and master the cutting-edge tools.

An Unbiased View Of The 6 Types of Supervised Learning

Supervised Machine Learning is an important area in today's world of big data. From your search history to your Facebook likes, many various types of data can be utilized with supervised learning. The field is constantly advancing, especially with the advent of deep neural networks, which can process image and speech data more accurately than before.

In this article, we will go over the detailed introduction of supervised learning along with its applications.

Supervised learning

Supervised learning is the process of training a model on training data, then validating its predictions against new data. The critical process allows machine learning algorithms to be used for various tasks, including fraud detection, image analysis, and recommendation engines.

Difference between Supervised and Unsupervised learning:

Supervised learning is when you have some data about the relationship between two or more variables and want to use that data to predict new values for unknown variables. This can be used for classification or regression problems.

Unsupervised learning is when you have no training data but want to make predictions based on relationships between variables. This type of prediction can be used for clustering or dimensionality reduction problems. A detailed explanation of ML types can be found in a Machine learning course in Delhi, co-developed with IBM.

Classification: 

The goal of classification is to determine the correct class labels for new instances (data) based on their relationship with examples stored in the training set. This type of learning is used when the labels represent categorical values, which can be either discrete or continuous.

For example, using classification, you can decide whether or not a creditor will default on a loan if you are planning to give them credit.

Regression: 

This type of learning aims to predict continuous variables given a set of known values for those variables (that have been previously determined).

By using training data, regression generates a single output value. This value is a probabilistic interpretation determined by assessing the correlation strength among the input parameters. For example, a regression can effectively forecast the price of a property based on its location, size, and other factors.

By using logistic regression, the output contains discrete values depending on a collection of independent factors. When dealing with non-linear and various choice limits, this strategy might fail. 

Linear Regression

Linear regression is one example of a supervised learning algorithm that uses a linear fit between the input and output variables. The output variable is called the prediction variable, and it's used to predict an outcome (for example, whether or not a patient will die). The model's coefficients are the x-intercepts of the line, and its slope represents how much change there is from y-intercept to y-intercept.

Logistic regression

When the dependent variable has a binary or categorical output, such as "yes" or "no," logistic regression is utilized. Additionally, logistic regression forecasts discrete values for variables since it is employed to address binary classification problems.

Naive Bayesian Model:

The Bayesian classification model is used for big finite datasets. It is a technique of assigning class labels that use a direct acyclic graph. The graph has one parent node and many child nodes. Moreover, each child node is expected to be independent and different from the parent. Since the supervised learning model in ML supports the development of classifiers in a basic and easy manner, it works well with smaller data sets.

This model is based on common data assumptions, such as the hypothesis that each attribute is independent. Despite its simplicity, this approach can be easily applied to complex situations.

Decision Trees: 

Decision Trees classify depending on the values of the features. They apply the Information Gain approach to figure out which component of the dataset provides the critical information, identify that as the root node, and so on until they can classify each dataset sample. Every branch of the Decision denotes a dataset feature. They are one of the most extensively used classification methods.

Random Forest Model:

Using an ensemble approach, the random forest model. It works by building several decision trees and then classifying each tree as it is generated.

The random forest algorithm uses many supervised learning techniques to reach a conclusion and is frequently referred to as an ensemble method. It also employs several decision trees to output the classification of individual trees. It is, therefore, commonly used in a variety of sectors.

Support Vector Machine (SVM): 

SVM algorithms are based on Vap Nik's statistical learning theory. Kernel functions, which are a crucial notion in most learning tasks, are often used. These techniques generate a hyper-plane to differentiate between the two classes.

Application of supervised learning

Speech recognition:

This is the type of application where you train the algorithm about your voice, and it recognizes you. The most popular real-world applications are virtual assistants like Google Assistant and Siri. 

Spam Detection:

This technology is used to prevent unreal or computer-based texts and E-Mails. Gmail includes an algorithm that learns the many terms that may be fraudulent and block those messages immediately.

Conclusion

To sum up, supervised learning is widely used in machine learning. They are primarily used to derive the relation between inputs and the output, e.g., the connection between the pixel of a photo (input) and its label, i.e., whether it depicts a school bus or car, which determines its usefulness for an object recognition task. In applications such as pattern recognition/computer vision, it is often labeled as a classification problem and falls under the discriminative learning domain. This is super simple for humans because we are used to looking at the world around us and labeling it by what we see. The goal of supervised learning is to create an algorithm using a dataset that can be used as a black box, and other algorithms can be applied to achieve similar results.

Top 7 Basic Methods Of Time Series Analysis and Forecasting

Introduction

Time series analysis has been used for over a century to analyze data collected at regular intervals over time. It could be stock prices, business performance, biological systems, and almost anything else that varies over time.

Time series analysis is a valuable tool for analyzing sales data and identifying trends. It can be used for applications such as identifying the surge that happens when subscribers receive their magazine. There are many types of time series analysis, and each one can help you approach your data in a different fashion. This article aims to discuss the common methods of time series analysis.

But before we delve into its methods, let's see what time series analysis means and its purpose.

What is Time series analysis?

The term "time series" refers to a sequence of measurements taken in time order over a period of time. Time series analysis is a method of analyzing time-dependent data. This is a relatively broad concept, so time series analysis methods vary widely in their specific techniques. It can be used to study economic trends, determine the effectiveness of a new drug, or predict future weather conditions.

The purpose of time series analysis is to examine how one variable changes over time. Generally, a time series is made up of data points plotted on a graph and connected with lines so that they form a curve or pattern. By looking at the pattern, we can determine whether it is random or has some underlying cause.

Common Methods of time series analysis:

There are many different ways of analyzing time-series data. One might be more suitable than the other, depending on the dataset or perhaps the objectives. Here we discuss some of the common methods of time series analysis.

Time series forecasting methods: 

Time series forecasting is the process of predicting future values based on historical values from a single series. A popular time series analysis method involves decomposing a time series into parts, such as trend, seasonal, or irregular components. 

Autocorrelation 

One method is known as autocorrelation, which measures the degree of dependence between two-time series. The concept is that if there's a strong correlation between two-time series, then they will tend to move together predictably. This method is used to identify trends or patterns that may not be immediately visible through visual inspection of the data.

Seasonality : 

Seasonality is another important feature of time series data. It provides a framework for the predictability of a variable at a specific time of day, month, season, or event. Seasonality can                ji   b be measured when an entity exhibits comparable values on a regular basis, i.e., after every specified time interval. For example, business sales of particular products surge during each festive season.

Stationarity: 

When the statistical features of a time series remain constant throughout time, we say that the series is stationary. In other words, the series' mean and variance remain constant. For example, stock prices are rarely static. 

Stationary is very crucial in time series; otherwise, a model that displays the data exhibits varying levels of accuracy at different points in time. As a result, professionals are expected to apply many strategies to turn a non-stationary time series into a stationary one before modeling.

Trends: 

The trend is a part of time series that depicts low-frequency variations in a time series after high and medium frequency changes have been filtered out. The entity's trend may decrease, increase, or remain stable depending on its nature and related influencing circumstances. Population, birth rate, and death rate are examples of dynamic entities and hence cannot form a stable time series.

Check out Learnbay’s Data science course in Delhi to understand time series analysis methods and apply them in various analysis projects. 

Modeling time-series data

There are various approaches to modeling time series data. Moving averages, exponential smoothing, and ARIMA are the three main types of time series models.

Moving Average (MA)

This model applies to univariate (single variable) time series. In a Moving Average model, the output (or future) variable is expected to have a linear relationship with the present and historical values. Hence, the new series is derived from the mean of the previous values. The MA model is ideal for recognizing and highlighting trends and trend cycles. 

Exponential Smoothing

Similar to MA, the Exponential Smoothing technique is applied to univariate series. The smoothing method involves applying an averaging function over a set of time, with the goal being to smooth out any irregularities to identify trends more easily. Depending on the trend and seasonality of the variable, you can use the simple (single) ES method or the advanced (double or triple) ES time series model.

Note: Moving averages (MA) are used when the trend in the data is known and can be removed from the data points. On the other hand, exponential smoothing (ES) is used when there is no known trend in the data, and multiple points must be averaged together.

Autoregressive integrated moving average (ARIMA) models

The ARIMA (auto-regressive integrated moving average) modeling approach is the most widely used time series method for analyzing long-run data series. This model works well with multivariate non-stationary data. It is popular because it gives easy-to-understand results and is simple to use. The ARIMA method is based on the concept of autocorrelation, autoregression, and moving averages. In the case of seasonal data, a variant of the model known as SARIMA (Seasonal ARIMA)  is used.

Finally, all-time series methods are particularly susceptible to outliers, so a thorough knowledge of these concepts can help you out when trying to model or forecast a time series.

Conclusion:

I hope this article has covered the fundamental time series analysis methods. You can use the techniques alone or in combination to forecast, understand patterns and trends in data, compare sample series, and study relationships between changes in variables over time to produce specific results. If you are interested in more advanced techniques used in time series analysis, consider taking a Data science certification course in Delhi to become an expert in various analysis methods.

How Data Science is Being Used for Real-world Business Challenges

Data science is used extensively in the corporate sector for many objectives. The variety of ways that organizations may employ data science is enormous and expanding across the finance, retail, manufacturing, and other sectors; nonetheless, all businesses use data science eventually to address issues. Business-focused data scientists know how to recognize which business-relevant challenges may be handled most effectively by their unique capabilities since they possess both technical and practical skills.

What is Data Science? A supply chain example

Data scientists work on issues that analytics can resolve, not "analytics problems." For instance, data science challenges are frequently used to discuss concerns with supply chain efficiency. Data scientists have even been dubbed the "superheroes of the supply chain" by Savi, a logistics company; food corporations, armies, and high-tech manufacturing organizations are just a few examples of industries that have used data science to increase supply chain effectiveness.

Businesses long recognize an effective supply chain as a key component of cost management. The ability to take into account the various variables that can impact the rate at which goods move through a supply chain is necessary to ensure supply chain efficiency; since these variables can be considered data, data scientists can use them to build models that can precisely predict future scenarios. Businesses increasingly turn to data scientists for this job as contemporary supply chains become more complicated. This is especially important when using blockchain to control the origin of expensive goods like precious stones.

Have a Look at the Data Analytics Course in Delhi to acquire practical knowledge of data science techniques in multiple industries. 

Five Key Data Science Problems 

The precise strategy a data scientist must employ differs based on the demands of their company. Data science is both a science and an art, and overcoming business obstacles requires using original thinking techniques.

Prototyping - Creating new services:

The prototype process is comparable to the innovation process, except that a completely new solution is being produced rather than one being replaced. Both internal services—like a financial institution utilizing machine learning to check for possible compliance breaches—and external, client-facing services are developed using prototypes. One well-known application of a service developed through prototyping is the usage of retail chatbots to direct customer journeys through a sales funnel.

Innovation: Replacing outdated approaches with fresh ones

Data scientists frequently contribute to their firms by creating new approaches to solve problems that have existed for a while and were previously handled by different strategies before the advent of data science. For instance, data scientists have been able to provide consumer demand estimates using "big data" analytics that is more accurate than those produced by earlier methods.

One of the most well-known instances of a data scientist offering a business a fresh perspective on an old problem is the book/movie "Moneyball," which explains how data science was used to replace conventional techniques in player recruiting in baseball. Ills.

Data-Value Exploration

Exploring data value is a project frequently undertaken by businesses that are just starting to employ data science. Numerous of these businesses own vast volumes of data but are unsure of which of them is helpful. The data scientist must thus investigate it for any possible prospects. Extensive testing is necessary for this kind of exploratory analysis, which also depends on the data scientist's experience and professional judgment.

These exploratory initiatives frequently need significant data preparation because most firms do not keep data organized. In these situations, the data scientist must put in a lot of effort to combine several data sources into a single, cohesive dataset that they can search through to uncover possibilities that have not yet been seen.

Problem-Solving in "Crisis

Every year, countless companies collapse due to unrecognized or undiscovered operational issues. Data scientists can frequently identify the root cause of problems that firms encounter. Factor analysis, a type of statistical analysis that enables data scientists to dissect a process into its component pieces (factors) to ascertain how much each one contributes to the issue, is one popular technique for achieving this.

Continuous Improvement:

The majority of entry-level data scientists' jobs are focused on continuous improvement. Modern management practice strongly emphasizes continuous improvement, and data science is a fundamental enabler of this philosophy. Making an existing data science project function more effectively is all that continuous improvement implies to data scientists themselves. For instance, many business-to-consumer (B2C) companies tailor their marketing to certain customer demographics using data science (segments). Data scientists must ascertain the characteristics that set apart a target audience group to create a statistical model that can identify those characteristics in a dataset. Data scientists must constantly enhance their company's models to maintain their competitiveness because many businesses employ this strategy.

RESOLVING TRAFFIC CONGESTION WITH THE HELP OF DATA SCIENCE

It is well known that traffic management in developing nations is difficult to resolve for various reasons, including political and economic reasons. Fortunately, this problem's technical or scientific dimensions are far simpler to solve than the other dimensions.

In this blog, I'll discuss some of the statistical methods employed and how "big data" was used to tackle this difficult issue; many of these methods are also useful for tackling business issues that arise in the real world.

As a result, it is more difficult to acquire traffic statistics due to their complexity. Therefore, an Intelligent Transportation System (ITS) emerges as a promising remedy for handling such complexity. In actuality, ITSs have been created and deployed in industrialized nations in various forms. However, they are rarely employed in most developing nations, largely because they are expensive to build, administer, and maintain.

The ITS project has three primary Business/Operational goals:

Effortless deployment

The primary data sources for the ITS system include end-user smartphone GPS data and GPS data from onboard GPS devices, traffic cameras, traffic sensors, etc. As a result, unlike previous ITSs, this approach does not need the installation of a system to gather data. This improved the ease of deployment for our system. However, this also meant that we had to develop a standard for the gathered GPS data before converting it to a single class for further analysis. For detailed information, check out  the trending Data Analytics course in Delhi. 

Effectiveness

According to experimental findings, a 2–3% GPS device penetration rate among all drivers is sufficient to estimate traffic flow velocity on specific road segments reliably and effectively. A disproportionately large number of narrow roads are solely appropriate for motorbikes in developing nations like Vietnam. Therefore, it was deemed that our ITS could adequately cover most of the urban road networks in HCMC using GPS motorbike data and GPS data from mobile applications.

In addition to the commercial goals, the ITS system sought to accomplish the following two main aims on a technological level:

To gather and effectively process traffic data from the numerous sources described previously, including cameras, sensors, GPS, and other devices on vehicles like automobiles, buses, taxis, motorbikes, etc., as well as from individual users via our own mobile app.

Modifying pertinent and already-developed algorithms in the field of transportation research to control traffic in crowded cities and alert end-users via a control center.

Economical system

The total solution has to be affordable for development and ongoing maintenance, much like any large-scale system. In this instance, we found that the operator's (the Ministry of Transportation) costs for creating, installing, and maintaining our system were significantly cheaper than those of current ITS models. We also concluded that the solution has to be simple for end customers to utilize. Fortunately, the cost of purchasing GPS devices for motorbikes in nations like Vietnam is inexpensive, and adopting such devices is generally common, making them an extremely accessible data source. Additionally, smart technologies (such as smartphones, tablets, etc.) are becoming more widely used and inexpensive in HCMC nowadays.

DATA SCIENCE USE CASES IN THE FIELD OF INSURANCE

Insurance firms are undergoing a fast digital revolution. With digital insurance transformation, insurers have access to more information. Data science assists insurance businesses in efficiently utilizing this data to drive more revenue and optimize their product offerings.

Data science may help insurers establish successful tactics for acquiring new clients, creating tailored products, analyzing risks, assisting underwriters, and implementing fraud detection systems, among other things. The data science use cases mentioned below show how the insurance sector is utilizing data science to expand their companies.

Customized Product Development

Using artificial intelligence and sophisticated analytics, insurers have extracted important insights from large amounts of demographic data, preferences, interactions, behaviour, lifestyle information, hobbies, and so on of their clients. Customers like a bespoke policy offer that is tailored to their specific requirements and lifestyle.

Data science may give precise insights about product features and pricing that appeal to a certain client segment. The capacity to create customized solutions that meet the needs of certain consumer segments distinguishes insurTechs from traditional insurance carriers.

Analytics for Claim Segmentation and Triage

Claim segmentation and triage analysis is the process of analyzing the complexity of each claim and awarding a score depending on the amount of complexity. This technique greatly assists insurance firms in reducing claim processing time by quickly tracking low-complexity claims and allocating more complex claims to a qualified adjuster with expertise in dealing with complexity. This method will also assist insurers in making better use of claim adjusters.

Fraud Detection

Insurance fraud causes huge financial losses for insurance firms. Subtle behavioural patterns can be traced using data science platforms to detect fraudulent actions.

Statistical models based on prior occurrences of fraudulent activity are typically fed into the fraud detection algorithm by insurance firms. Predictive modelling approaches may be used to discover fraud incidents by evaluating the linkages between suspicious actions and recognizing previously undetected fraud schemes. To gain a profound understanding of fraud detection, refer to the Data Analytics course in Delhi, for working professionals. 

Healthcare Insurance

Healthcare insurance is a widely used insurance practice in every country. The insurance covers all expenditures incurred as a result of sickness, accident, incapacity, or death. Governments in most nations actively support healthcare insurance schemes. This domain cannot withstand the enormous effect of data analytics applications in the digital era when information influences all sectors of the world.

Insurance claims data, membership and provider data, benefits and health records, client and case data, internet data, and other types of data are gathered, structured, processed, and turned into relevant insights for the medical insurance business. As a result, cost reductions, service quality, fraud detection and prevention, and improved consumer interaction may all improve significantly. 

Optimization of Pricing

Data scientists assist insurers in dynamically quoting rates that are closely tied to the customer's pricing sensitivity. Price optimization boosts client retention and loyalty.

Prediction of Lifetime Value

Client lifetime value (CLV) is a sophisticated concept that quantifies the worth of a client to a company in terms of the difference between revenues earned and costs paid throughout a customer's whole future relationship. Customer behavior data is commonly used to anticipate CLV and estimate customer profitability for insurers. Modern predictive analytics systems perform a comprehensive and well-rounded assessment of many data sources to make sensible pricing and policy decisions. 

Behaviour-based models are widely used to anticipate cross-selling and retention. 'Recency,' the monetary value of a client to a corporation, and 'frequency' are acknowledged as important variables in determining future income. The algorithms aggregate and analyze all of the data to create the forecast. This allows for predicting customer behaviour and attitudes, policy maintenance, or a policy surrender. Furthermore, the CLV forecast can be useful for building marketing strategies because it gives customer insights.

Finding Outlier Claims

Predictive analytics in insurance can assist in recognizing claims that become high-cost losses unexpectedly, often known as outlier claims. Analytics tools can be used by P&C insurers to automatically review previous claims for similarities and notify claims specialists. Early warning of probable losses or challenges can assist insurers in lowering these outlier claims. Predictive analytics for outlier claims does not have to be used simply after a claim has been submitted. Insurance companies can use outlier claim data to make plans to deal with similar claims in the future.

Role of Data Scientist in Military and Intelligence

Data science has carved its relevance in the military and intelligence fields at a time when the world's superpowers are continually improving their military might and strategy. Military leaders of the world's superpowers realize the important importance of data science in the military, as well as the reality that the battlefield of the twenty-first century will be led by whoever leads artificial intelligence. There is broad agreement that having a workforce capable of adapting to rapid technological change is critical.

Given the advancement of technology, which has substantially empowered the military, the past and present military systems are dramatically different. From beefed-up and ripped cops to more fit intellectuals, there is a transition in overall look and intelligence. The reason for this shift is that, in addition to physical strength, modern military, law enforcement, and intelligence operations need a vast amount of data analysis acquired via a variety of channels such as the internet, satellites, phones, and so on. Such data is created on a daily, minute-by-minute, or even second-by-second basis on a local and international scale.

Big Data is used in military logistics to feed the machine.

Military logistical operations are critical to the survival of the fighters. Civilian logistical activities are critical to global commerce. As it is now known, logistics originated as a science concerned with military supplies and supply lines. With contemporary hostilities taking place on the other side of the world more often than normal, getting Reaper parts and fuel to forward airstrips is more important than ever. Data scientists are now attempting to enhance military supply chain management, much like their civilian counterparts at FedEx. For detailed information on ML models and algorithms, refer to the Machine learning course in Delhi.

Data is required for modern warfare

ARGUS-IS and other current sophisticated sensor suites have remarkable powers that verge on black magic. According to Defensetech, the military is having trouble hiring someone to mine all of the data collected by these devices. In order to better understand how to manage the flow of data, the Department of Defense has sought out organizations as disparate as National Geographic and ESPN. This is where the function of a skilled data scientist in the military comes into play. Automation is one. method for dealing with the quick influx. Data scientists use machine intelligence technologies, such as the ARGUS-IS, to filter through data sources and identify possible targets for human examination.

Military data scientists confront a unique challenge that civilian data scientists do not, namely dealing with purposeful obfuscation and interference with data collection. Spoofing, jamming, and deceit are common in military and terrorist interactions. Advanced data scientists continuously work to build algorithms that can identify such deception. Conventional forces are embracing the Internet of Things, which allows formerly "dumb" hardware like tanks and weaponry to have built-in logic and networking capabilities, hence increasing the quantity of data accessible. Counter-terrorism officers are now using civilian data sources like surveillance. Cameras, cell phone networks, and public records databases expand access to intelligence and more efficiently monitor opponents.

Force Tracking Using the Internet of Things (IoT)

On the battlefield, knowing your opponent is just modestly more beneficial than knowing your own troops. For example, during the Persian Gulf and Iraq Wars, a spate of friendly fire, or "blue-on-blue," incidents demonstrated the perils of failing to keep attack units fully informed of each other's position and capabilities. In response to similar concerns in the US military, a "Blue Force Tracker" program was developed. Blue Force Tracker (BFT) installs a GPS receiver, a satellite transceiver, and software in tanks and other military vehicles via the Internet of Things.

The position and other status data from the vehicle are uplinked to military communications satellites and then merged with data from other vehicles and systems to provide a comprehensive real-time picture of all assets in the area. In addition to reducing inadvertent fratricide, BFT enables commanders to monitor force deployments and optimize routes depending on geography and tactical planning.

Action Confirms Interpretation And Detection

However, gathering and analyzing data from drones and other sensor platforms is only half the fight. The second side of the equation is providing actionable intelligence to soldiers and operatives in the field on time. Connecting field operations and troops to the network is a huge effort in its own right, but it pales in contrast to the complexity of providing data swiftly and clearly in high-stress scenarios. Big data has become a potent tool on modern conflict battlefields, like a double-edged sword. The insights gleaned from data may give firms a major competitive edge. Nevertheless, the stream of data can obscure critical information under a barrage of less important updates.

Hope you this post gave you an insight into the world of data science and military services.

Optimization Concept in Data Science

From a mathematical standpoint, the three pillars of data science that we need to grasp relatively well are linear algebra, statistics, and optimization, which are employed in almost all data science techniques. A solid foundation in linear algebra is required to comprehend optimization principles.

What exactly is Optimization?

According to Wikipedia, optimization is a task in which you maximize or minimize a real function by methodically selecting input values from a permitted set and determining the function's value. We constantly look for the best answer when we talk about optimization. So, suppose someone is interested in a functional form (e.g., f(x)) and is seeking to discover the optimal solution for this functional form. What does "best" mean now? He may be said to be interested in either reducing or enhancing this functional form.

Components of an Optimization Problem

The objective function(f(x)): The first element is an objective function f(x) that we are attempting to maximize or decrease. In general, we are discussing minimization difficulties. This is because we may turn a maximizing issue with f(x) into a minimization problem with -f (x). So we can look at minimization issues without losing generality.

Decision variables(x): The decision variables are the variables that we may use to minimize the function. As a result, we write this as min f. (x).

Constraints(a ≤ x ≤ b): The constraint, which simply limits this x to a set, is the third component.

As a result, anytime you look at an optimization problem, you should search for these three components.

Depending on the purpose functions, decision variables, and restrictions are used:

If the decision variable (x) is continuous:

If a variable x has an unlimited number of values, it is said to be continuous. In this example, x can have an unlimited number of values ranging from -2 to 2. (-2, 2)

min f(x), x ∈ (-2, 2)

Linear programming problem: This sort of problem exists when the decision variable (x) is continuous, the objective function (f) is linear, and all restrictions are also linear. 

Nonlinear programming problem: This sort of problem exists if the decision variable(x) stays continuous and if either the objective function(f) or the restrictions are non-linear. As a result, a non-linear programming problem occurs when either the aim or the constraints become non-linear.

Learn this technical concept with the help of the best Machine learning course in Delhi. 

If the decision variable (x) is an integer variable:

 Then any values with a fractional component of 0 (zero), such as -3, -2, 1, 0, 10, 100, are integers.

Linear integer programming problem: A linear integer programming problem exists when the decision variable (x) is an integer variable, the objective function (f) is linear, and all constraints are linear. As a result, the decision variables in this example are integers, the objective function is linear, and the constraints are likewise linear.

Nonlinear integer programming problem: If the decision variable(x) stays integer, the problem is known as a non-linear integer programming problem; but, if either the objective function(f) or the constraints are non-linear, the problem is known as a non-linear integer programming problem. As a result, a non-linear programming problem occurs when either the aim or the constraints become non-linear.

Binary integer programming problem: If the decision variable(x) can only accept binary values such as 0 and 1, then it's called a binary integer programming problem."

min f(x), x ∈ [0, 1]

If the decision variable(x) is a mixed variable: 

If we combine both a continuous and an integer variable, we get a mixed variable.

min f(x1, x2), x1 ∈ [0, 1, 2, 3] and x2 ∈ (-2, 2)

Mixed-integer linear programming problem: A mixed-integer linear programming problem exists when the decision variable (x) is a mixed variable, the objective function (f) is linear, and all constraints are linear. As a result, the choice variables are mixed in this example, the objective function is linear, and the constraints are likewise linear.

Mixed-integer nonlinear programming problem: If either the objective function(f) or the constraints are non-linear, this issue is known as a mixed-integer nonlinear programming problem. As a result, a non-linear programming problem occurs when either the aim or the constraints become non-linear.
