Mr. Levan Dvalishvili Chief (Software Architect) at solarspace.io said Hands down the most developer friendly package that I have worked with.. A+++++

platform we tried out Metronic. I can not overestimate the impact Metronic has had. Its accelerated development 3x and reduced QA issues by 50%. If you add up the reduced need for design time/resources, the increase in dev speed and the reduction in QA, it’s probably saved us $100,000 on this project alone, and I plan to use it for all platforms moving forward. The flexibility of the design has also allowed us to put out a better looking & working platform and reduced my headaches by 90%. Thank you KeenThemes! Jonathan Bartlett, Metronic Customer

Metronic is an incredible template. Even with purchasing an extended license, the cost savings is immeasurable. The code & CSS is well organized and while it is feature rich, it is not bloated. It was quickly integrated into our relatively complex product and had ready-made UX for our many use cases. Where we needed to extend functionality, this system made it incredibly easy. A tremendous job by the Metronic team.  Fatica, Metronic Customer

How To Process Quality AI Training Data For Machine Learning?

Are you constantly thinking of AI for your company? Do you feel that there is a necessity for AI in the current business world? Do you wish to see a successful boost in return on investment for your business? Who doesn't? Everyone wants to see more profit, however, fuel is needed to run the vehicle. Do you possibly have a database? The majority of companies currently are struggling to create an AI-ready Data Set. It's not difficult to create a data set on your own, however, it is a bit out of the area for a lot of businesses. Let me help you find the right area.

AI Training Dataset is basically the collection of data. Data sets can be as an array of tables that contain all data from statistical studies or it could be in shape of matrice which is an arrangement of rectangular columns and rows. The columns represent a specific variable, while each row represents a particular member of the data set. It is essential to have training data sets since they are the primary component that makes a training algorithm work. There could be sudden failures with your work if the data set isn't high enough. The quality and amount of your machine learning training data has to do with the performance of your project as the quality of your data.

Training data is what's that is used to train machines to recognize patterns. AI assists them in learning the pattern and operate in similarly for each one. The creation of AI training Data is now in progress. The High-Quality AI training dataset fulfills all needs for a particular learning purpose in the most complex tasks.

We agree that AI has made the process of generation easier on its own hands, however there are situations in which annotating data must be based on some human judgments. The most important thing is that individuals come to a consensus conclusion as to which portion of recorded data is the correct one. So, making annotation guidelines may not be as simple as one would imagine. This is why our Quality Check team perfectly guides you through the process.

What is AI Training Data?

Do you think it's a difficult concept for the layman? I'll make use of simple words to help you understand the significance and function. It is basically information utilized to train the AI machines in recognizing a repetitive pattern. AI aids the machines to understand the patterns and work in exactly the same way when it comes to the pattern. The process of creating AI training Datat is in the process of being created. Quality AI training dataset fulfills all the requirements for an exact learning goal, even for the most challenging tasks.

The set of data doesn't contain only data collection for text. The overall Data Set Collection includes Image Dataset Collection, Video Dataset Collection, Speech Data Collection as well as Video Data Collection. Let's take an easy ride through these data sets.

1.Speech/Audio Data Collection-

Each human's voice and speech pattern is different. They differ in their intonation the pace, pronunciation, and the dialect. These aspects make it difficult to create artificially-generated Speech Recognition Dataset technology. AI Speech Data Collection recognizes the way people speak and pronounce the instructions for assistants to speak, the way people react and respond on speech recognition software, the way people pronounce and pronounce the pre-defined phrases, as well as how easily sentences are understood when used by people from different backgrounds and from distinct background noise. This constantly changing nature demands the best AI training for the audio systems you use.

2. Video Dataset Collection-

To develop AI-based surveillance motion detection or gesture-based guidance systems it is crucial to gather a large amount of quality training data. These include motion sequences, gestures scenes, sports and objects, animals and other. AI is focused on quality check videos, recordings of video as well as lighting conditions. It also has an extensive collection in video sets and customised training data.

3. Image Dataset Collection-

Every AI system has to be trained using appropriate and model-specific photo dates for recognizing and assessing images for machine learning purpose. It should cover a vast range in Image Dataset collection as well as annotations for every types of deep learning and machine learning applications. An extensive array of images must be made available in order to create computer vision models using the largest images and deep-learning images.

4. Text Dataset Collection-

Text Dataset Collection or OCR Training Dataset takes a much more than any other type of dataset collection. This collection requires an end-to-end number of languages. This is unique in it is the model of machine learning they aid to construct. It's not simple for machine learning models to process huge volumes of structured text data and work with it in this method. To get a better ROI, you need to have large quantities from multilingual texts are needed are required for you machine learning.

What does Quality of Data mean?

Do you remember when the teacher you were with handed your an examination? How did you respond? You've probably gathered all of the data related to this particular subject from reliable sources. Also, high-quality data analysis is based on the search for the best information to use in machine learning. It is not possible for every type of data you gathered to complete the project could be used for machine learning. The data you collect is of sufficient quality to be used in Machine Learning algorithms that drive the development of artificial intelligence.

We are confident in the quality and accuracy of our AI Training Data is determined by:

Accuracy - The accuracy of any data set is determined by comparing it with any data set of reference.

Completeness- Then, we must ensure the accuracy of our data to ensure that it doesn't contain any insufficient or missing values. There shouldn't be any loopholes that remain in our database.

Its timeliness - Data should not be out of date. It must be up-to-date.

Consistency- When does consistency persist in any data set? It's when data is in various storage areas and could be considered to be comparable.

Integrity- The final key area to consider is integrity. High integrity adheres to the syntax (format type, format range, format) of its definition.

Four-step process to guide the user to Data Cleansing

Establish the Benchmarks by eliminating unneeded observations - Every data set when combined with multiple datasets can result in redundant data. Eliminating duplicate observations aids in improving the accuracy of the data. Invalid and duplicate values have be eliminated.

Correct the structural data errors that occur when measuring, transferring data, or in other similar scenarios are known as structural errors. They can be caused by typos in the names of attributes and attributes, or the same attribute but with the wrong name, incorrectly labeled classes, i.e. distinct classes that should be the same , or with inconsistent the capitalization.

Take care of the outliers that aren't needed. Outliers are a source of trouble for several models. Let's say linear regression models are less tolerant of extreme outliers than the decision tree model. It is not advisable to remove outliers unless we have an actual reason to eliminate them. Sometimes, eliminating them can improve the performance. The result could be harmful for us. Thus, it is necessary to have an argument to eliminate the outliers, like unusual measurements that are not likely to be a part of the actual data.

Resolving Missing DataIn the case of missing data, Data could be very useful. It could be an indicator of something important. This is a difficult issue when it comes to machine learning. Your entire program could fail if you simply overlook the missing observation. We should be aware of missing data and flag it. Make use of the technique of marking and filling. This method will be beneficial to you.

Our Working Process

Consulting- GTS's experts will help you establish strategic business objectives and the results to your plan. The proper consultation is offered by clients in a series of meetings.

The Data Collecting / Data collection is the most important stage in creating OCR Datasets . Our team can assist you collect data employing a variety of methods and in-house experience as per the requirements.

Training as well as Data annotation The team is trained , and annotations are used to gain valuable insights to train AI.

Feedback and EvaluationOur goal is to make your satisfaction our main goal. So, all data is put through rigorous quality checks before being is then sent to final deployment in order to ensure that the accuracy is at a minimum.

Data Visualization With DataTables.js and Highcharts.js

In this tutorial, you’ll learn how to visualize data by taking advantage of the DataTables.js and Highcharts.js JavaScript libraries.

Here’s what we're going to build (check out the larger version for a better experience):

Required Libraries

For the purposes of this example, we’ll have to load the following libraries in our pen:

jQuery

DataTables.js

Highcharts.js

With that in mind, if you look under the Settings tab, you’ll see that I've included one external CSS file:

In the same way, I've also included four external JavaScript files:

Note: we had to add jQuery to our project because DataTables.js is a jQuery plugin. However, keep in mind that Highcharts.js is a pure JavaScript library, and thus doesn’t require jQuery.

The HTML

To kick things off we define an element with the class of container which contains two sub-elements:

A table with 26 rows. The first row refers to the table headers th, while the other 25 rows carry country details. The source of our data for this example is worldometers.info.

An empty div which will hold the chart.

Here’s the HTML structure:

<div class="container"> <table id="dt-table"> <thead> <tr> <th>Country</th> <th>Population (2017)</th> <th>Density (P/Km²)</th> <th>Med. Age</th> </tr> </thead> <tbody> <tr> <td>China</td> <td>1,409,517,397</td> <td>150</td> <td>37</td> </tr> <!-- 24 more rows here --> </tbody </table> <div id="chart"></div> </div>

It’s worth mentioning that, for the sake of simplicity, we’ve specified the aforementioned hard-coded table data. In a real project though, the table might be created dynamically.

With the markup ready, and a background color added for clarity, the project looks like this:

The CSS

At this point, we define some basic styles, like so:

.container { display: flex; flex-wrap: wrap; align-items: center; padding: 0 10px; } #dt-table_wrapper { width: 35%; margin-right: 2%; } #chart { width: 63%; } table { text-align: left; } @media screen and (max-width: 1200px) { #dt-table_wrapper, #chart { width: 100%; } #dt-table_wrapper { margin-right: 0; } }

It’s important to understand that:

The #dt-table_wrapper doesn’t exist in our markup. It’s added by the DataTables as soon as we initialize it.

While we define a few basic rules for small screens, note that the demo won’t be fully responsive. There are a lot of things we can do to make the table and chart look better on small screens. For example, for DataTables there’s a Responsive extension available, but that’s beyond the scope of this tutorial.

With the CSS in place, let’s see how the project looks. We won’t see a big difference yet because we haven’t initialized the libraries:

The JavaScript

Now for the JavaScript window in our pen. When the DOM is ready, the init function is executed; this function triggers other sub-functions:

function init() { const table = $("#dt-table").DataTable(); const tableData = getTableData(table); createHighcharts(tableData); setTableEvents(table); }

As you’ll see, each of these sub-functions accomplishes a certain task.

Initializing DataTables

The first step is to convert our table into a “DataTables” table. We can do this with just one line of code: $("#dt-table").DataTable();

If we now look at the table, we’ll notice that it has adopted the capabilities of a DataTables table, ie: we can sort it, search it, and so on. Have a play with it in the following demo:

Now, as you can see, DataTables applies a default sorting to the table. If needed, we can customize this behavior.

Extracting Table Data

The next step is to grab the table data and build the chart. We don’t want all the table data. In fact, if you look back at the finished version of our demo, you’ll notice that the chart only contains data from the first three columns (Country, Population, Density).

With that in mind, in order to retrieve the required data, we’ll take advantage of the DataTables API. The function responsible for this behavior is the following one:

function getTableData(table) { const dataArray = [], countryArray = [], populationArray = [], densityArray = []; // loop table rows table.rows({ search: "applied" }).every(function() { const data = this.data(); countryArray.push(data[0]); populationArray.push(parseInt(data[1].replace(/\,/g, ""))); densityArray.push(parseInt(data[2].replace(/\,/g, ""))); }); // store all data in dataArray dataArray.push(countryArray, populationArray, densityArray); return dataArray; }

Inside this function, we iterate through the table rows and for each row, we grab the target column data and store them in the associated arrays. Finally, all those arrays are stored inside another array. 

Here’s a quick visualization of the master (i.e. dataArray) array:

Before moving on, it’s important to understand one thing. By default, the getTableData function should collect data from all the table rows. But then, if we search the table for something specific, only the rows that match should be collected and processed. To accomplish these things, we pass an argument to the rows function. Specifically, an object with the search: "applied" property value. 

Again note that if we don’t pass this object, we’ll always collect data from all the table rows (test it). For more information about the properties that we can pass to this object, be sure to look at this page. 

Building the Chart

Now that we have the desired data, we’re ready to build the chart. This will contain two nested charts, one Column chart and one Spline chart. 

Here’s the corresponding function:

function createHighcharts(data) { Highcharts.setOptions({ lang: { thousandsSep: "," } }); Highcharts.chart("chart", { title: { text: "DataTables to Highcharts" }, subtitle: { text: "Data from worldometers.info" }, xAxis: [ { categories: data[0], labels: { rotation: -45 } } ], yAxis: [ { // first yaxis title: { text: "Population (2017)" } }, { // secondary yaxis title: { text: "Density (P/Km²)" }, min: 0, opposite: true } ], series: [ { name: "Population (2017)", color: "#0071A7", type: "column", data: data[1], tooltip: { valueSuffix: " M" } }, { name: "Density (P/Km²)", color: "#FF404E", type: "spline", data: data[2], yAxis: 1 } ], tooltip: { shared: true }, legend: { backgroundColor: "#ececec", shadow: true }, credits: { enabled: false }, noData: { style: { fontSize: "16px" } } }); }

Don’t be overwhelmed by the code above! Without doubt the best way to understand how it works is to try it. Plus, you should definitely read the documentation. Anyhow, let’s briefly highlight the key concepts:

The x-axis contains all the countries.

We define two y-axes. The first one holds all the population values, while the second one includes all the available densities.

If our chart doesn’t contain any data a message appears. Note that we’re able to customize the message text through the lang object.

With the charts in place, let’s again look at our progress:

Synchronizing the Table and Charts

In the previous section, we built the chart based on the table data, but there’s still no full synchronization between the table and chart. To prove it, go back to the last demo and change the ordering (sorting) of the table, or search for something. You’ll notice that the chart doesn’t react to table changes.  

To fix this, we’ll take advantage of the DataTables draw event. This event fires each time the table gets updated. So as soon as we modify the table we should recollect the table data and reconstruct the chart.

Here’s the tricky thing though. The draw event also fires during the table pagination; there’s no reason to rebuild the chart during this process. Ideally, we should prevent this behavior. Thankfully, there’s the page event which helps us accomplish this task.

Here’s the code that implements the desired functionality:

let draw = false; function setTableEvents(table) { // listen for page clicks table.on("page", () => { draw = true; }); // listen for updates and adjust the chart accordingly table.on("draw", () => { if (draw) { draw = false; } else { const tableData = getTableData(table); createHighcharts(tableData); } }); }

Now that both table and chart are synchronized, if we make a “bad” search, we’ll see the following messages:

The final version of our project:

Browser Support

Both plugins have great browser support (DataTables support, Highcharts support), so you can expect that this demo will work well in all recent browsers. 

Again keep in mind that this demo isn’t optimized for small screens. 

Lastly, as usual, we use Babel to compile the ES6 code down to ES5. 

Conclusion

That’s it folks! We managed to visualize our data by combining two popular and powerful JavaScript libraries. 

Now that you’re familiar with the process, go ahead and elaborate the functionality of the final demo. For instance, try to add custom filters to the table.

As always, if you have any questions or if there’s anything else you would like to see as a next step to this tutorial, let me know in the comments below.
