EASYLIBPAL IMPLEMENTATION:

Step 1: Define the Problem

First, we need to define the problem we want to solve. For this POC, let's assume we want to predict house prices based on various features like the number of bedrooms, square footage, and location.

Step 2: Choose an Appropriate Algorithm

Given our problem, a supervised learning algorithm like linear regression would be suitable. We'll use Scikit-learn, a popular library for machine learning in Python, to implement this algorithm.

Step 3: Prepare Your Data

We'll use Pandas to load and prepare our dataset. This involves cleaning the data, handling missing values, and splitting the dataset into training and testing sets.

Step 4: Implement the Algorithm

Now, we'll use Scikit-learn to implement the linear regression algorithm. We'll train the model on our training data and then test its performance on the testing data.

Step 5: Evaluate the Model

Finally, we'll evaluate the performance of our model using metrics like Mean Squared Error (MSE) and R-squared.

Python Code POC

```python

import numpy as np

import pandas as pd

from sklearn.model_selection import train_test_split

from sklearn.linear_model import LinearRegression

from sklearn.metrics import mean_squared_error, r2_score

# Load the dataset

data = pd.read_csv('house_prices.csv')

# Prepare the data

X = data'bedrooms', 'square_footage', 'location'

y = data['price']

# Split the data into training and testing sets

X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2, random_state=42)

# Create and train the model

model = LinearRegression()

model.fit(X_train, y_train)

# Make predictions

predictions = model.predict(X_test)

# Evaluate the model

mse = mean_squared_error(y_test, predictions)

r2 = r2_score(y_test, predictions)

print(f'Mean Squared Error: {mse}')

print(f'R-squared: {r2}')

"""Preprocesses the dataset."""

# Implement data preprocessing steps here

return dataset

def split_data(self, X, y, test_size=0.2):

"""Splits the dataset into training and testing sets."""

return train_test_split(X, y, test_size=test_size)

```

Additional Algorithms

Easylibpal should support a wider range of algorithms. This includes decision trees, random forests, and gradient boosting machines.

```python

from sklearn.tree import DecisionTreeClassifier

from sklearn.ensemble import RandomForestClassifier

from sklearn.ensemble import GradientBoostingClassifier

class Easylibpal:

# Existing code...

def fit(self, X, y):

# Existing code...

elif self.algorithm == 'Decision Tree':

self.model = DecisionTreeClassifier()

elif self.algorithm == 'Random Forest':

self.model = RandomForestClassifier()

elif self.algorithm == 'Gradient Boosting':

self.model = GradientBoostingClassifier()

# Add more algorithms as needed

```

User-Friendly Features

To make Easylibpal even more user-friendly, consider adding features like:

"""Evaluates the model using accuracy and classification report."""

y_pred = self.predict(X_test)

print("Accuracy:", accuracy_score(y_test, y_pred))

print(classification_report(y_test, y_pred))

def tune_hyperparameters(self, X, y, param_grid):

"""Tunes the model's hyperparameters using GridSearchCV."""

grid_search = GridSearchCV(self.model, param_grid, cv=5)

grid_search.fit(X, y)

self.model = grid_search.best_estimator_

```

Easylibpal leverages the power of Python and its rich ecosystem of AI and machine learning libraries, such as scikit-learn, to implement the classic algorithms.

ABSTRACTION AND ESSENTIAL COMPLEXITY

- Essential Complexity: This refers to the inherent complexity of the problem domain, which cannot be reduced regardless of the programming language or framework used. It includes the logic and algorithm needed to solve the problem. For example, the essential complexity of sorting a list remains the same across different programming languages.

- Accidental Complexity: This is the complexity introduced by the choice of programming language, framework, or libraries. It can be reduced or eliminated through abstraction. For instance, using a high-level API in Python can hide the complexity of lower-level operations, making the code more readable and maintainable.

HOW EASYLIBPAL ABSTRACTS COMPLEXITY

Easylibpal aims to reduce accidental complexity by providing a high-level API that encapsulates the details of each classic AI algorithm. This abstraction allows users to apply these algorithms without needing to understand the underlying mechanisms or the specifics of the algorithm's implementation.

- Simplified Interface: Easylibpal offers a unified interface for applying various algorithms, such as Linear Regression, Logistic Regression, SVM, Naive Bayes, and K-NN. This interface abstracts the complexity of each algorithm, making it easier for users to apply them to their datasets.

- Runtime Fusion: By evaluating sub-expressions and sharing them across multiple terms, Easylibpal can optimize the execution of algorithms. This approach, similar to runtime fusion in abstract algorithms, allows for efficient computation without duplicating work, thereby reducing the computational complexity.

- Focus on Essential Complexity: While Easylibpal abstracts away the accidental complexity; it ensures that the essential complexity of the problem domain remains at the forefront. This means that while the implementation details are hidden, the core logic and algorithmic approach are still accessible and understandable to the user.

To implement Easylibpal, one would need to create a Python class that encapsulates the functionality of each classic AI algorithm. This class would provide methods for loading datasets, preprocessing data, and applying the algorithm with minimal configuration required from the user. The implementation would leverage existing libraries like scikit-learn for the actual algorithmic computations, abstracting away the complexity of these libraries.

Here's a conceptual example of how the Easylibpal class might be structured for applying a Linear Regression algorithm:

```python

class Easylibpal:

def __init__(self, dataset):

self.dataset = dataset

# Load and preprocess the dataset

def apply_linear_regression(self, target_column):

# Abstracted implementation of Linear Regression

# This method would internally use scikit-learn or another library

# to perform the actual computation, abstracting the complexity

pass

# Usage

Easylibpal = Easylibpal(dataset='your_dataset.csv')

result = Easylibpal.apply_linear_regression(target_column='target')

```

This example demonstrates the concept of Easylibpal by abstracting the complexity of applying a Linear Regression algorithm. The actual implementation would need to include the specifics of loading the dataset, preprocessing it, and applying the algorithm using an underlying library like scikit-learn.

Easylibpal abstracts the complexity of classic AI algorithms by providing a simplified interface that hides the intricacies of each algorithm's implementation. This abstraction allows users to apply these algorithms with minimal configuration and understanding of the underlying mechanisms. Here are examples of specific algorithms that Easylibpal abstracts:

Easylibpal abstracts the complexity of feature selection for classic AI algorithms by providing a simplified interface that automates the process of selecting the most relevant features for each algorithm. This abstraction is crucial because feature selection is a critical step in machine learning that can significantly impact the performance of a model. Here's how Easylibpal handles feature selection for the mentioned algorithms:

To implement feature selection in Easylibpal, one could use scikit-learn's `SelectKBest` or `RFE` classes for feature selection based on statistical tests or model coefficients. Here's a conceptual example of how feature selection might be integrated into the Easylibpal class for Linear Regression:

```python

from sklearn.feature_selection import SelectKBest, f_regression

from sklearn.linear_model import LinearRegression

class Easylibpal:

def __init__(self, dataset):

self.dataset = dataset

# Load and preprocess the dataset

def apply_linear_regression(self, target_column):

# Feature selection using SelectKBest

selector = SelectKBest(score_func=f_regression, k=10)

X_new = selector.fit_transform(self.dataset.drop(target_column, axis=1), self.dataset[target_column])

# Train Linear Regression model

model = LinearRegression()

model.fit(X_new, self.dataset[target_column])

# Return the trained model

return model

# Usage

Easylibpal = Easylibpal(dataset='your_dataset.csv')

model = Easylibpal.apply_linear_regression(target_column='target')

```

This example demonstrates how Easylibpal abstracts the complexity of feature selection for Linear Regression by using scikit-learn's `SelectKBest` to select the top 10 features based on their statistical significance in predicting the target variable. The actual implementation would need to adapt this approach for each algorithm, considering the specific characteristics and requirements of each algorithm.

To implement feature selection in Easylibpal, one could use scikit-learn's `SelectKBest`, `RFE`, or other feature selection classes based on the algorithm's requirements. Here's a conceptual example of how feature selection might be integrated into the Easylibpal class for Logistic Regression using RFE:

```python

from sklearn.feature_selection import RFE

from sklearn.linear_model import LogisticRegression

class Easylibpal:

def __init__(self, dataset):

self.dataset = dataset

# Load and preprocess the dataset

def apply_logistic_regression(self, target_column):

# Feature selection using RFE

model = LogisticRegression()

rfe = RFE(model, n_features_to_select=10)

rfe.fit(self.dataset.drop(target_column, axis=1), self.dataset[target_column])

# Train Logistic Regression model

model.fit(self.dataset.drop(target_column, axis=1), self.dataset[target_column])

# Return the trained model

return model

# Usage

Easylibpal = Easylibpal(dataset='your_dataset.csv')

model = Easylibpal.apply_logistic_regression(target_column='target')

```

This example demonstrates how Easylibpal abstracts the complexity of feature selection for Logistic Regression by using scikit-learn's `RFE` to select the top 10 features based on their importance in the model. The actual implementation would need to adapt this approach for each algorithm, considering the specific characteristics and requirements of each algorithm.

EASYLIBPAL HANDLES DIFFERENT TYPES OF DATASETS

Easylibpal handles different types of datasets with varying structures by adopting a flexible and adaptable approach to data preprocessing and transformation. This approach is inspired by the principles of tidy data and the need to ensure data is in a consistent, usable format before applying AI algorithms. Here's how Easylibpal addresses the challenges posed by varying dataset structures:

One Type in Multiple Tables

When datasets contain different variables, the same variables with different names, different file formats, or different conventions for missing values, Easylibpal employs a process similar to tidying data. This involves identifying and standardizing the structure of each dataset, ensuring that each variable is consistently named and formatted across datasets. This process might include renaming columns, converting data types, and handling missing values in a uniform manner. For datasets stored in different file formats, Easylibpal would use appropriate libraries (e.g., pandas for CSV, Excel files, and SQL databases) to load and preprocess the data before applying the algorithms.

Multiple Types in One Table

For datasets that involve values collected at multiple levels or on different types of observational units, Easylibpal applies a normalization process. This involves breaking down the dataset into multiple tables, each representing a distinct type of observational unit. For example, if a dataset contains information about songs and their rankings over time, Easylibpal would separate this into two tables: one for song details and another for rankings. This normalization ensures that each fact is expressed in only one place, reducing inconsistencies and making the data more manageable for analysis.

Data Semantics

Easylibpal ensures that the data is organized in a way that aligns with the principles of data semantics, where every value belongs to a variable and an observation. This organization is crucial for the algorithms to interpret the data correctly. Easylibpal might use functions like `pivot_longer` and `pivot_wider` from the tidyverse or equivalent functions in pandas to reshape the data into a long format, where each row represents a single observation and each column represents a single variable. This format is particularly useful for algorithms that require a consistent structure for input data.

Messy Data

Dealing with messy data, which can include inconsistent data types, missing values, and outliers, is a common challenge in data science. Easylibpal addresses this by implementing robust data cleaning and preprocessing steps. This includes handling missing values (e.g., imputation or deletion), converting data types to ensure consistency, and identifying and removing outliers. These steps are crucial for preparing the data in a format that is suitable for the algorithms, ensuring that the algorithms can effectively learn from the data without being hindered by its inconsistencies.

To implement these principles in Python, Easylibpal would leverage libraries like pandas for data manipulation and preprocessing. Here's a conceptual example of how Easylibpal might handle a dataset with multiple types in one table:

```python

import pandas as pd

# Load the dataset

dataset = pd.read_csv('your_dataset.csv')

# Normalize the dataset by separating it into two tables

song_table = dataset'artist', 'track'.drop_duplicates().reset_index(drop=True)

song_table['song_id'] = range(1, len(song_table) + 1)

ranking_table = dataset'artist', 'track', 'week', 'rank'.drop_duplicates().reset_index(drop=True)

# Now, song_table and ranking_table can be used separately for analysis

```

This example demonstrates how Easylibpal might normalize a dataset with multiple types of observational units into separate tables, ensuring that each type of observational unit is stored in its own table. The actual implementation would need to adapt this approach based on the specific structure and requirements of the dataset being processed.

CLEAN DATA

Easylibpal employs a comprehensive set of data cleaning and preprocessing steps to handle messy data, ensuring that the data is in a suitable format for machine learning algorithms. These steps are crucial for improving the accuracy and reliability of the models, as well as preventing misleading results and conclusions. Here's a detailed look at the specific steps Easylibpal might employ:

1. Remove Irrelevant Data

The first step involves identifying and removing data that is not relevant to the analysis or modeling task at hand. This could include columns or rows that do not contribute to the predictive power of the model or are not necessary for the analysis .

2. Deduplicate Data

Deduplication is the process of removing duplicate entries from the dataset. Duplicates can skew the analysis and lead to incorrect conclusions. Easylibpal would use appropriate methods to identify and remove duplicates, ensuring that each entry in the dataset is unique.

3. Fix Structural Errors

Structural errors in the dataset, such as inconsistent data types, incorrect values, or formatting issues, can significantly impact the performance of machine learning algorithms. Easylibpal would employ data cleaning techniques to correct these errors, ensuring that the data is consistent and correctly formatted.

4. Deal with Missing Data

Handling missing data is a common challenge in data preprocessing. Easylibpal might use techniques such as imputation (filling missing values with statistical estimates like mean, median, or mode) or deletion (removing rows or columns with missing values) to address this issue. The choice of method depends on the nature of the data and the specific requirements of the analysis.

5. Filter Out Data Outliers

Outliers can significantly affect the performance of machine learning models. Easylibpal would use statistical methods to identify and filter out outliers, ensuring that the data is more representative of the population being analyzed.

6. Validate Data

The final step involves validating the cleaned and preprocessed data to ensure its quality and accuracy. This could include checking for consistency, verifying the correctness of the data, and ensuring that the data meets the requirements of the machine learning algorithms. Easylibpal would employ validation techniques to confirm that the data is ready for analysis.

To implement these data cleaning and preprocessing steps in Python, Easylibpal would leverage libraries like pandas and scikit-learn. Here's a conceptual example of how these steps might be integrated into the Easylibpal class:

```python

import pandas as pd

from sklearn.impute import SimpleImputer

from sklearn.preprocessing import StandardScaler

class Easylibpal:

def __init__(self, dataset):

self.dataset = dataset

# Load and preprocess the dataset

def clean_and_preprocess(self):

# Remove irrelevant data

self.dataset = self.dataset.drop(['irrelevant_column'], axis=1)

# Deduplicate data

self.dataset = self.dataset.drop_duplicates()

# Fix structural errors (example: correct data type)

self.dataset['correct_data_type_column'] = self.dataset['correct_data_type_column'].astype(float)

# Deal with missing data (example: imputation)

imputer = SimpleImputer(strategy='mean')

self.dataset['missing_data_column'] = imputer.fit_transform(self.dataset'missing_data_column')

# Filter out data outliers (example: using Z-score)

# This step requires a more detailed implementation based on the specific dataset

# Validate data (example: checking for NaN values)

assert not self.dataset.isnull().values.any(), "Data still contains NaN values"

# Return the cleaned and preprocessed dataset

return self.dataset

# Usage

Easylibpal = Easylibpal(dataset=pd.read_csv('your_dataset.csv'))

cleaned_dataset = Easylibpal.clean_and_preprocess()

```

This example demonstrates a simplified approach to data cleaning and preprocessing within Easylibpal. The actual implementation would need to adapt these steps based on the specific characteristics and requirements of the dataset being processed.

VALUE DATA

Easylibpal determines which data is irrelevant and can be removed through a combination of domain knowledge, data analysis, and automated techniques. The process involves identifying data that does not contribute to the analysis, research, or goals of the project, and removing it to improve the quality, efficiency, and clarity of the data. Here's how Easylibpal might approach this:

Domain Knowledge

Easylibpal leverages domain knowledge to identify data that is not relevant to the specific goals of the analysis or modeling task. This could include data that is out of scope, outdated, duplicated, or erroneous. By understanding the context and objectives of the project, Easylibpal can systematically exclude data that does not add value to the analysis.

Data Analysis

Easylibpal employs data analysis techniques to identify irrelevant data. This involves examining the dataset to understand the relationships between variables, the distribution of data, and the presence of outliers or anomalies. Data that does not have a significant impact on the predictive power of the model or the insights derived from the analysis is considered irrelevant.

Automated Techniques

Easylibpal uses automated tools and methods to remove irrelevant data. This includes filtering techniques to select or exclude certain rows or columns based on criteria or conditions, aggregating data to reduce its complexity, and deduplicating to remove duplicate entries. Tools like Excel, Google Sheets, Tableau, Power BI, OpenRefine, Python, R, Data Linter, Data Cleaner, and Data Wrangler can be employed for these purposes .

Examples of Irrelevant Data

- Personal Identifiable Information (PII): Data such as names, addresses, and phone numbers are irrelevant for most analytical purposes and should be removed to protect privacy and comply with data protection regulations .

- URLs and HTML Tags: These are typically not relevant to the analysis and can be removed to clean up the dataset.

- Boilerplate Text: Excessive blank space or boilerplate text (e.g., in emails) adds noise to the data and can be removed.

- Tracking Codes: These are used for tracking user interactions and do not contribute to the analysis.

To implement these steps in Python, Easylibpal might use pandas for data manipulation and filtering. Here's a conceptual example of how to remove irrelevant data:

```python

import pandas as pd

# Load the dataset

dataset = pd.read_csv('your_dataset.csv')

# Remove irrelevant columns (example: email addresses)

dataset = dataset.drop(['email_address'], axis=1)

# Remove rows with missing values (example: if a column is required for analysis)

dataset = dataset.dropna(subset=['required_column'])

# Deduplicate data

dataset = dataset.drop_duplicates()

# Return the cleaned dataset

cleaned_dataset = dataset

```

This example demonstrates how Easylibpal might remove irrelevant data from a dataset using Python and pandas. The actual implementation would need to adapt these steps based on the specific characteristics and requirements of the dataset being processed.

Detecting Inconsistencies

Easylibpal starts by detecting inconsistencies in the data. This involves identifying discrepancies in data types, missing values, duplicates, and formatting errors. By detecting these inconsistencies, Easylibpal can take targeted actions to address them.

Handling Formatting Errors

Formatting errors, such as inconsistent data types for the same feature, can significantly impact the analysis. Easylibpal uses functions like `astype()` in pandas to convert data types, ensuring uniformity and consistency across the dataset. This step is crucial for preparing the data for analysis, as it ensures that each feature is in the correct format expected by the algorithms.

Handling Missing Values

Missing values are a common issue in datasets. Easylibpal addresses this by consulting with subject matter experts to understand why data might be missing. If the missing data is missing completely at random, Easylibpal might choose to drop it. However, for other cases, Easylibpal might employ imputation techniques to fill in missing values, ensuring that the dataset is complete and ready for analysis.

Handling Duplicates

Duplicate entries can skew the analysis and lead to incorrect conclusions. Easylibpal uses pandas to identify and remove duplicates, ensuring that each entry in the dataset is unique. This step is crucial for maintaining the integrity of the data and ensuring that the analysis is based on distinct observations.

Handling Inconsistent Values

Inconsistent values, such as different representations of the same concept (e.g., "yes" vs. "y" for a binary variable), can also pose challenges. Easylibpal employs data cleaning techniques to standardize these values, ensuring that the data is consistent and can be accurately analyzed.

To implement these steps in Python, Easylibpal would leverage pandas for data manipulation and preprocessing. Here's a conceptual example of how these steps might be integrated into the Easylibpal class:

```python

import pandas as pd

class Easylibpal:

def __init__(self, dataset):

self.dataset = dataset

# Load and preprocess the dataset

def clean_and_preprocess(self):

# Detect inconsistencies (example: check data types)

print(self.dataset.dtypes)

# Handle formatting errors (example: convert data types)

self.dataset['date_column'] = pd.to_datetime(self.dataset['date_column'])

# Handle missing values (example: drop rows with missing values)

self.dataset = self.dataset.dropna(subset=['required_column'])

# Handle duplicates (example: drop duplicates)

self.dataset = self.dataset.drop_duplicates()

# Handle inconsistent values (example: standardize values)

self.dataset['binary_column'] = self.dataset['binary_column'].map({'yes': 1, 'no': 0})

# Return the cleaned and preprocessed dataset

return self.dataset

# Usage

Easylibpal = Easylibpal(dataset=pd.read_csv('your_dataset.csv'))

cleaned_dataset = Easylibpal.clean_and_preprocess()

```

This example demonstrates a simplified approach to handling inconsistent or messy data within Easylibpal. The actual implementation would need to adapt these steps based on the specific characteristics and requirements of the dataset being processed.

Statistical Imputation

Statistical imputation involves replacing missing values with statistical estimates such as the mean, median, or mode of the available data. This method is straightforward and can be effective for numerical data. For categorical data, mode imputation is commonly used. The choice of imputation method depends on the distribution of the data and the nature of the missing values.

Model-Based Imputation

Model-based imputation uses machine learning models to predict missing values. This approach can be more sophisticated and potentially more accurate than statistical imputation, especially for complex datasets. Techniques like K-Nearest Neighbors (KNN) imputation can be used, where the missing values are replaced with the values of the K nearest neighbors in the feature space.

Using SimpleImputer in scikit-learn

The scikit-learn library provides the `SimpleImputer` class, which supports both statistical and model-based imputation. `SimpleImputer` can be used to replace missing values with the mean, median, or most frequent value (mode) of the column. It also supports more advanced imputation methods like KNN imputation.

To implement these imputation techniques in Python, Easylibpal might use the `SimpleImputer` class from scikit-learn. Here's an example of how to use `SimpleImputer` for statistical imputation:

```python

from sklearn.impute import SimpleImputer

import pandas as pd

# Load the dataset

dataset = pd.read_csv('your_dataset.csv')

# Initialize SimpleImputer for numerical columns

num_imputer = SimpleImputer(strategy='mean')

# Fit and transform the numerical columns

dataset'numerical_column1', 'numerical_column2' = num_imputer.fit_transform(dataset'numerical_column1', 'numerical_column2')

# Initialize SimpleImputer for categorical columns

cat_imputer = SimpleImputer(strategy='most_frequent')

# Fit and transform the categorical columns

dataset'categorical_column1', 'categorical_column2' = cat_imputer.fit_transform(dataset'categorical_column1', 'categorical_column2')

# The dataset now has missing values imputed

```

This example demonstrates how to use `SimpleImputer` to fill in missing values in both numerical and categorical columns of a dataset. The actual implementation would need to adapt these steps based on the specific characteristics and requirements of the dataset being processed.

Model-based imputation techniques, such as Multiple Imputation by Chained Equations (MICE), offer powerful ways to handle missing data by using statistical models to predict missing values. However, these techniques come with their own set of limitations and potential drawbacks:

1. Complexity and Computational Cost

Model-based imputation methods can be computationally intensive, especially for large datasets or complex models. This can lead to longer processing times and increased computational resources required for imputation.

2. Overfitting and Convergence Issues

These methods are prone to overfitting, where the imputation model captures noise in the data rather than the underlying pattern. Overfitting can lead to imputed values that are too closely aligned with the observed data, potentially introducing bias into the analysis. Additionally, convergence issues may arise, where the imputation process does not settle on a stable solution.

3. Assumptions About Missing Data

Model-based imputation techniques often assume that the data is missing at random (MAR), which means that the probability of a value being missing is not related to the values of other variables. However, this assumption may not hold true in all cases, leading to biased imputations if the data is missing not at random (MNAR).

4. Need for Suitable Regression Models

For each variable with missing values, a suitable regression model must be chosen. Selecting the wrong model can lead to inaccurate imputations. The choice of model depends on the nature of the data and the relationship between the variable with missing values and other variables.

5. Combining Imputed Datasets

After imputing missing values, there is a challenge in combining the multiple imputed datasets to produce a single, final dataset. This requires careful consideration of how to aggregate the imputed values and can introduce additional complexity and uncertainty into the analysis.

6. Lack of Transparency

The process of model-based imputation can be less transparent than simpler imputation methods, such as mean or median imputation. This can make it harder to justify the imputation process, especially in contexts where the reasons for missing data are important, such as in healthcare research.

Despite these limitations, model-based imputation techniques can be highly effective for handling missing data in datasets where a amusingness is MAR and where the relationships between variables are complex. Careful consideration of the assumptions, the choice of models, and the methods for combining imputed datasets are crucial to mitigate these drawbacks and ensure the validity of the imputation process.

Masterlist

New York part four

Chapter 7

The light of the morning was peeking through the hotel curtains. Austin was still sleeping. It was a whirlwind last night. You had, had two glasses of champagne. You know Austin had a glass, but you didn't know if he drank it.  

Getting out of bed, you walk as quietly as you can to the bathroom.  Do you close the bathroom door?  You are just peeing.  He's seen every inch of you.  You decide to close the door so as not to wake him.  The bathroom was charming, elegant, and quaint.  The walls, the sink, and the toilet were white.  The sink had a black vanity.  It is all tied to the gold and white speckled black marble flooring. There was a painting with all the bathroom colors and some blue and grey above the towel rack.  This bathroom had a huge shower.  You and Austin have taken a few together in there.  There is a substantial tub with a black and white vase full of white and sky-blue flowers.  

After finishing, you flush and wash your hands. You stop to listen. It didn't seem like he was awake.  Again, you quietly make your way to the kitchen part of the room, closing the bedroom door behind you.  In the fully stocked kitchen, you rummage for coffee pods to put in the Keruig.  After finding a cup and the pod you wanted, you made coffee.  Taking your cup, you sat at the dining table and opened your laptop.  You took a sip and checked your emails.  You had four emails from your editor and one from the author.  You checked the author’s one first.

The Email:

Dear Ms. Y/LN,

The Cover of the book is fabulous. Thomas has given me the green light to start the second book. Here’s hoping for a best seller. Thank you for your hard work.

Yours Truly,

AN/LN

You felt such joy, and this made you smile. Then, not knowing Austin had been staring at you for a few minutes, he starts, “Good Morning, Beautiful.”  Jumping at his deep husky voice. “Austin Butler, you scared me,” you reply, holding your hand to your heart. “What were you smiling about?” he questioned with a quizzical smile. You were looking him up and down. He was wearing a bathrobe. You knew he had nothing on under it.  He sees your eyes.  "Do you like what you see?" His smile darkens.  Your face erupts with red.  Your body melts into a euphoric puddle when he smiles at you.  You look into his eyes, "It depends on whatcha got under there," you purr.  Parting his lips, he answered, "Come back to bed, and I'll show you."  Austin had told you he liked morning sex better than any.  It started his day off right.

He leaned against the doorway, waiting for you to get up. You slowly got up, showing no underwear. He squinted his eyes and licked his lips.  “I need you now, Y/N,” he demanded.  Your mouth twitches into a grin, and you bite your lower lip.  He clenches his jaw as he takes a step toward you.  You are wearing his t-shirt that he was wearing last night.  To him, you looked incredibly sexy in it.  He took another step forward.  You are now entirely standing.  He is close enough to you that you can feel his breath.  You look down, and his now standing-at-attention manhood is peeking through his robe.  He takes another step looking down at you, and you must step back.  He puts one arm around your waist to keep you from falling.  You hit the table as he puts his other hand on the table.  His eyes darken to a grey color.  His eyes blaze with passion as he lifts you.  He gently puts you on the table.  Moving his face closer toward you, he presses his lips to yours.  Slowly forcing your lips apart, he thrust his tongue inward.  Touching and swirling around each other's tongues, he places his thumb on your clit.  Gently rotating it around.  You gasp at the sensation.  You want to lie down, but his other arm is around you.  Arching your back, he leans with you.  He lifts your shirt and suckles your breast.  He slowly inserts two fingers into your mama's cavern. He is pushing them in briskly, going faster and faster.   Your hips are moving more quickly.  Breathing becomes faster, and Austin won't let you come up for air.   A sound escapes your mouth, Austin still thrashing your tongue, laughs.  He can feel how close you are.  He knows.  You need air.  Coming up for air, you feel all your muscles tighten just before you let go.  Feeling your orgasm, Austin doesn't hesitate, and he pushes his manhood into you.  He makes an animalistic gurgle noise.  You moan and hum as he enters. You are still finishing.   He no longer kisses you. His face is leaning against your shoulder, and his mouth nibbles on it.  You have your hands on his butt, pushing him.  Having wrapped your legs around his, you can feel every inch.  He pounds harder, faster, and deeper.  Groaning from his stomach, he tilts his head back to release his hot liquid. You were squeezing him from the inside. He lets out a small whimper.  He needed that.  Standing there, the two of you lock eyes.  For what seemed like forever, he just stared at you.  Feeling your face flush, “What?” you ask.  

Whispering, “Nothing, I just can’t believe you are mine.”  “Austin, I was going to tell you something.”  “Can it wait? I have a full day planned for us.”  “Yeah, It can wait.”

A few hours later, you and Austin are going to Liberty Island.  You have never been, and Austin thought it might be fun for you two to go.  He brought his camera just in case.  You were on the ferry leaning against the railing.  Austin was behind you, holding the rail in front of you.  Your hair was flying in the wind.  Because of his height, he was towering over you like a mountain towers over the valley.  You felt safe.  "Hey, let me take some pictures." He offered.  "What do I have to do?" You questioned.  "Nothing, just stand there like you are." He answered.  You looked out into the harbor.  Austin starts taking your picture from different angles.  He was serious about photography.  "Look to the side, that's good," he directed.  "I am getting some serious awesome shots."  "Now look over your shoulder to me, yeah, just like that.  My goddess, you look gorgeous.  I can't wait to develop these."  He stood up and gently kissed your cheek.  "Did you just call me a goddess?" You teased. "Yes, you are my goddess," he said, matter of factly. 

Austin made sure your day was complete.  Liberty Island, Ellis Island, Top of the rock (you were so scared, but Austin being there made you feel better), he took pictures of you at Times Square, at lunch, he took you to his favorite sushi restaurant, you went to Central Park, walked around holding hands and finally had dinner at Mulino.  He paid for everything.  You tried to pay once, but he got a little upset.  He kissed your forehead to let you know that it was ok.

Austin was not done spoiling you.  He knew Christmas was your favorite holiday, and since you were here at his request, he took you to see the Christmas tree at Rockefeller center. 

It was the most beautiful tree in the whole world.  As you were looking at the tree, Austin was behind you.  He was on one knee.  "Goddess, I need to ask you something.  Turn around beautiful," his voice shaking as he said it.  You turn around as tears well up in your eyes, "Oh. AUSTIN!!"  "Y/N L/N, I know we have only known each other for a few months, but I feel like I have known you much longer.  I find myself thinking about you all the time.  I physically need you to be mine, that's obvious.  More than that, I need you to be mine in every aspect of my life. Will you do me the honors and be my wife?"  He stood up, holding a ring between his thumb and index finger.  It was a quaint ring, not gaudy.  You liked simple jewelry.  You and Ashley had a conversation about it when you went shopping.  In fact, you had pointed out a ring that you would wear.  It was the ring.  Silver with a small diamond, a peridot stone for Austin, and your birthstone.  It was gorgeous, yet simple.  It was the perfect ring for you.  How did he get it made this quick?  Staring at him, tears running down your cheeks.  Poor Austin looked anxious.  He was waiting to hear a yes, no, maybe, or kick him in the balls.  He wanted an answer.  "This is what I wanted to talk to you about.  I will," you speak in a muffled voice.  He examined your face, "Is that a yes?" he quizzed, bending down to look you in the eye.  You lick your lips, "Yes, Butler, Yes!" You declared.  "Yes?" he inquires as he lifts you off your feet, turning you around.  He kisses you in the most loving way.  "My goddess."  He puts the ring on your finger, and he kisses your hand.

Using Vector Index And Multilingual Embeddings in BigQuery

The Tower of Babel reborn? Using vector search and multilingual embeddings in BigQuery Finding and comprehending reviews in a customer’s favourite language across many languages can be difficult in today’s globalised marketplace. Large datasets, including reviews, may be managed and analysed with BigQuery.

In order to enable customers to search for products or company reviews in their preferred language and obtain results in that language, google cloud describe a solution in this blog post that makes use of BigQuery multilingual embeddings, vector index, and vector search. These technologies translate textual data into numerical vectors, enabling more sophisticated search functions than just matching keywords. This improves the relevancy and accuracy of search results.

Vector Index

A data structure called a Vector Index is intended to enable the vector index function to carry out a more effective vector search of embeddings. In order to enhance search performance when vector index is possible to employ a vector index, the function approximates nearest neighbour search method, which has the trade-off of decreasing recall and yielding more approximate results.

Authorizations and roles

You must have the bigquery tables createIndex IAM permission on the table where the vector index is to be created in order to create one. The bigquery tables deleteIndex permission is required in order to drop a vector index. The rights required to operate with vector indexes are included in each of the preset IAM roles listed below:

Establish a vector index

The build VECTOR INDEX data definition language (DDL) statement can be used to build a vector index.

Access the BigQuery webpage.

Run the subsequent SQL statement in the query editor

Swap out the following:

The vector index you’re creating’s name is vector index. The index and base table are always created in the same project and dataset, therefore these don’t need to be included in the name.

Dataset Name: The dataset name including the table.

Table Name: The column containing the embeddings data’s name in the table.

Column Name:The column name containing the embeddings data is called Column name. ARRAY is the required type for the column. No child fields may exist in the column. The array’s items must all be non null, and each column’s values must have the same array dimensions. Stored Column Name: the vector index’s storage of a top-level table column name. A column cannot have a range type. If a policy tag is present in a column or if the table has a row-level access policy, then stored columns are not used. See Store columns and pre-filter for instructions on turning on saved columns.

Index Type:The vector index building algorithm is denoted by Index type. There is only one supported value: IVF. By specifying IVF, the vector index is constructed as an inverted file index (IVF). An IVF splits the vector data according to the clusters it created using the k-means method. These partitions allow the vector search function to search the vector data more efficiently by limiting the amount of data it must read to provide a result.

Distance Type: When utilizing this index in a vector search, distance type designates the default distance type to be applied. COSINE and EUCLIDEAN are the supported values. The standard is EUCLIDEAN.

While the distance utilised in the vector search function may vary, the index building process always employs EUCLIDEAN distance for training.

The Diatance type value is not used if you supply a value for the distance type argument in the vector search function. Num Lists: an INT64 value that is equal to or less than 5,000 that controls the number of lists the IVF algorithm generates. The IVF method places data points that are closer to one another on the same list, dividing the entire data space into a number of lists equal to num lists. A smaller number for num lists results in fewer lists with more data points, whereas a bigger value produces more lists with fewer data points.

To generate an effective vector search, utilise num list in conjunction with the fraction lists to search argument in the vector list function. Provide a low fraction lists to search value to scan fewer lists in vector search and a high num lists value to generate an index with more lists if your data is dispersed among numerous small groups in the embedding space. When your data is dispersed in bigger, more manageable groups, use a fraction lists to search value that is higher than num lists. Building the vector index may take longer if you use a high num lists value.

In addition to adding another layer of refinement and streamlining the retrieval results for users, google cloud’s solution translates reviews from many languages into the user’s preferred language by utilising the Translation API, which is easily integrated into BigQuery. Users can read and comprehend evaluations in their preferred language, and organisations can readily evaluate and learn from reviews submitted in multiple languages. An illustration of this solution can be seen in the architecture diagram below.

Google cloud took business metadata (such address, category, and so on) and review data (like text, ratings, and other attributes) from Google Local for businesses in Texas up until September 2021. There are reviews in this dataset that are written in multiple languages. Google cloud’s approach allows consumers who would rather read reviews in their native tongue to ask inquiries in that language and obtain the evaluations that are most relevant to their query in that language even if the reviews were originally authored in a different language.

For example, in order to investigate bakeries in Texas, google cloud asked, “Where can I find Cantonese-style buns and authentic Egg Tarts in Houston?” It is difficult to find relevant reviews among thousands of business profiles for these two unique and frequently available bakery delicacies in Asia, but less popular in Houston.

Google cloud system allows users to ask questions in Chinese and get the most appropriate answers in Chinese, even if the reviews were written in other languages at first, such Japanese, English, and so on. This solution greatly improves the user’s ability to extract valuable insights from reviews authored by people speaking different languages by gathering the most pertinent information regardless of the language used in the reviews and translating them into the language requested by the user.

Consumers may browse and search for reviews in the language of their choice without encountering any language hurdles; you can then utilise Gemini to expand the solution by condensing or categorising the reviews that were sought for. By simply adding a search function, you may expand the application of this solution to any product, business reviews, or multilingual datasets, enabling customers to find the answers to their inquiries in the language of their choice. Try it out and think of additional useful data and AI tools you can create using BigQuery!
