Book excerpt: The objective of this data science project is to analyze and predict customer behavior in the groceries market using Python and create a graphical user interface (GUI) using PyQt. The project encompasses various stages, starting from exploring the dataset and visualizing the distribution of features to RFM analysis, K-means clustering, predicting clusters with machine learning algorithms, and implementing a GUI for user interaction. The first step in this project involves exploring the dataset. We load the dataset containing information about customers' purchases in the groceries market and examine its structure. We check for missing values and perform data preprocessing if necessary, ensuring the dataset is ready for analysis. This initial exploration allows us to gain a better understanding of the data and its characteristics. Following the dataset exploration, we conduct exploratory data analysis (EDA). This step involves visualizing the distribution of different features within the dataset. By creating histograms, box plots, scatter plots, and other visualizations, we gain insights into the patterns, trends, and relationships within the data. EDA helps us identify outliers, understand feature distributions, and uncover potential correlations between variables. After the EDA phase, we move on to RFM analysis. RFM stands for Recency, Frequency, and Monetary analysis. In this step, we calculate three key metrics for each customer: recency (how recently a customer made a purchase), frequency (how often a customer made purchases), and monetary value (how much a customer spent). RFM analysis allows us to segment customers based on their purchasing behavior, identifying high-value customers and those who require re-engagement strategies. Once we have the clusters, we can utilize machine learning algorithms to predict the cluster for new or unseen customers. We train various models, including logistic regression, support vector machines, decision trees, k-nearest neighbors, random forests, gradient boosting, naive Bayes, adaboost, XGBoost, and LightGBM, on the clustered data. These models learn the patterns and relationships between customer features and their assigned clusters, enabling us to predict the cluster for new customers accurately. To evaluate the performance of our models, we utilize metrics such as accuracy, precision, recall, and F1-score. These metrics allow us to measure the models' predictive capabilities and compare their performance across different algorithms and preprocessing techniques. By assessing the models' performance, we can select the most suitable model for cluster prediction in the groceries market analysis. In addition to the analysis and prediction components, this project aims to provide a user-friendly interface for interaction and visualization. To achieve this, we implement a GUI using PyQt, a Python library for creating desktop applications. The GUI allows users to input new customer data and predict the corresponding cluster based on the trained models. It provides visualizations of the analysis results, including cluster distributions, confusion matrices, and decision boundaries. The GUI allows users to select different machine learning models and preprocessing techniques through radio buttons or dropdown menus. This flexibility empowers users to explore and compare the performance of various models, enabling them to choose the most suitable approach for their specific needs. The GUI's interactive nature enhances the usability of the project and promotes effective decision-making based on the analysis results. In conclusion, this project combines data science methodologies, including dataset exploration, visualization, RFM analysis, K-means clustering, predictive modeling, and GUI implementation, to provide insights into customer behavior and enable accurate cluster prediction in the groceries market. By leveraging these techniques, businesses can enhance their marketing strategies, improve customer targeting and retention, and ultimately drive growth and profitability in a competitive market landscape. The project's emphasis on user interaction and visualization through the GUI ensures that businesses can easily access and interpret the analysis results, making informed decisions based on data-driven insights.

Book excerpt: PROJECT 1: RFM ANALYSIS AND K-MEANS CLUSTERING: A CASE STUDY ANALYSIS, CLUSTERING, AND PREDICTION ON RETAIL STORE TRANSACTIONS WITH PYTHON GUI The dataset used in this project is the detailed data on sales of consumer goods obtained by ‘scanning’ the bar codes for individual products at electronic points of sale in a retail store. The dataset provides detailed information about quantities, characteristics and values of goods sold as well as their prices. The anonymized dataset includes 64.682 transactions of 5.242 SKU's sold to 22.625 customers during one year. Dataset Attributes are as follows: Date of Sales Transaction, Customer ID, Transaction ID, SKU Category ID, SKU ID, Quantity Sold, and Sales Amount (Unit price times quantity. For unit price, please divide Sales Amount by Quantity). This dataset can be analyzed with RFM analysis and can be clustered using K-Means algorithm. The machine learning models used in this project to predict clusters as target variable are K-Nearest Neighbor, Random Forest, Naive Bayes, Logistic Regression, Decision Tree, Support Vector Machine, LGBM, Gradient Boosting, XGB, and MLP. Finally, you will plot boundary decision, distribution of features, feature importance, cross validation score, and predicted values versus true values, confusion matrix, learning curve, performance of the model, scalability of the model, training loss, and training accuracy. PROJECT 2: DATA SCIENCE FOR GROCERIES MARKET ANALYSIS, CLUSTERING, AND PREDICTION WITH PYTHON GUI RFM analysis used in this project can be used as a marketing technique used to quantitatively rank and group customers based on the recency, frequency and monetary total of their recent transactions to identify the best customers and perform targeted marketing campaigns. The idea is to segment customers based on when their last purchase was, how often they've purchased in the past, and how much they've spent overall. Clustering, in this case K-Means algorithm, used in this project can be used to place similar customers into mutually exclusive groups; these groups are known as “segments” while the act of grouping is known as segmentation. Segmentation allows businesses to identify the different types and preferences of customers/markets they serve. This is crucial information to have to develop highly effective marketing, product, and business strategies. The dataset in this project has 38765 rows of the purchase orders of people from the grocery stores. These orders can be analyzed with RFM analysis and can be clustered using K-Means algorithm. The machine learning models used in this project to predict clusters as target variable are K-Nearest Neighbor, Random Forest, Naive Bayes, Logistic Regression, Decision Tree, Support Vector Machine, LGBM, Gradient Boosting, XGB, and MLP. Finally, you will plot boundary decision, distribution of features, feature importance, cross validation score, and predicted values versus true values, confusion matrix, learning curve, performance of the model, scalability of the model, training loss, and training accuracy.

This book was released on 2023-07-07 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this case study, we will explore RFM (Recency, Frequency, Monetary) analysis and K-means clustering techniques for retail store transaction data. RFM analysis is a powerful method for understanding customer behavior by segmenting them based on their transaction history. K-means clustering is a popular unsupervised machine learning algorithm used for grouping similar data points. We will leverage these techniques to gain insights, perform customer segmentation, and make predictions on retail store transactions. The case study involves a retail store dataset that contains transaction records, including customer IDs, transaction dates, purchase amounts, and other relevant information. This dataset serves as the foundation for our RFM analysis and clustering. RFM analysis involves evaluating three key aspects of customer behavior: recency, frequency, and monetary value. Recency refers to the time since a customer's last transaction, frequency measures the number of transactions made by a customer, and monetary value represents the total amount spent by a customer. By analyzing these dimensions, we can segment customers into different groups based on their purchasing patterns. Before conducting RFM analysis, we need to preprocess and transform the raw transaction data. This includes cleaning the data, aggregating it at the customer level, and calculating the recency, frequency, and monetary metrics for each customer. These transformed RFM metrics will be used for segmentation and clustering. Using the RFM metrics, we can apply clustering algorithms such as K-means to group customers with similar behaviors together. K-means clustering aims to partition the data into a predefined number of clusters based on their feature similarities. By clustering customers, we can identify distinct groups with different purchasing behaviors and tailor marketing strategies accordingly. K-means is an iterative algorithm that assigns data points to clusters in a way that minimizes the within-cluster sum of squares. It starts by randomly initializing cluster centers and then iteratively updates them until convergence. The resulting clusters represent distinct customer segments based on their RFM metrics. To determine the optimal number of clusters for our K-means analysis, we can employ elbow method. This method help us identify the number of clusters that provide the best balance between intra-cluster similarity and inter-cluster dissimilarity. Once the K-means algorithm has assigned customers to clusters, we can analyze the characteristics of each cluster. This involves examining the RFM metrics and other relevant customer attributes within each cluster. By understanding the distinct behavior patterns of each cluster, we can tailor marketing strategies and make targeted business decisions. Visualizations play a crucial role in presenting the results of RFM analysis and K-means clustering. We can create various visual representations, such as scatter plots, bar charts, and heatmaps, to showcase the distribution of customers across clusters and the differences in RFM metrics between clusters. These visualizations provide intuitive insights into customer segmentation. The objective of this data science project is to analyze and predict customer behavior in the groceries market using Python and create a graphical user interface (GUI) using PyQt. The project encompasses various stages, starting from exploring the dataset and visualizing the distribution of features to RFM analysis, K-means clustering, predicting clusters with machine learning algorithms, and implementing a GUI for user interaction.

This book was released on 2023-07-04 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we conducted a customer segmentation, clustering, and prediction analysis using Python. We began by exploring the customer dataset, examining its structure and contents. The dataset contained various features such as demographic, behavioral, and transactional attributes. To ensure accurate analysis and modeling, we performed data preprocessing steps. This involved handling missing values, removing duplicates, and addressing any data quality issues that could impact the results. We also split the dataset into features (X) and the target variable (y) for prediction tasks. Since the dataset had features with different scales and units, we applied feature scaling techniques. This process standardized or normalized the data, ensuring that all features contributed equally to the analysis. We then performed regression analysis on the "PURCHASESTRX" feature, which represents the number of purchase transactions made by customers. To begin the regression analysis, we first prepared the dataset by handling missing values, removing duplicates, and addressing any data quality issues. We then split the dataset into features (X) and the target variable (y), with "PURCHASESTRX" being the target variable for regression. We selected appropriate regression algorithms for modeling, such as Linear Regression, Random Forest, Naïve Bayes, KNN, Decision Trees, Support Vector, Ada Boost, Catboost, Gradient Boosting, Extreme Gradient Boosting, Light Gradient Boosting, and Multi-Layer Perceptron regressors. After training and evaluation, we analyzed the performance of the regression models. We examined the metrics to determine how accurately the models predicted the number of purchase transactions made by customers. A lower MAE and RMSE indicated better predictive performance, while a higher R2 score indicated a higher proportion of variance explained by the model. Based on the analysis, we provided insights and recommendations. These could include identifying factors that significantly influence the number of purchase transactions, understanding customer behavior patterns, or suggesting strategies to increase customer engagement and transaction frequency. Next, we focused on customer segmentation using unsupervised machine learning techniques. K-means clustering algorithm was employed to group customers into distinct segments. The optimal number of clusters was determined using KElbowVisualizer. To gain insights into the clusters, we visualized them 3D space. Dimensionality PCA reduction technique wasused to plot the clusters on scatter plots or 3D plots, enabling us to understand their separations and distributions. We then interpreted the segments by analyzing their characteristics. This involved identifying the unique features that differentiated one segment from another. We also pinpointed the key attributes or behaviors that contributed most to the formation of each segment. In addition to segmentation, we performed clusters prediction tasks using supervised machine learning techniques. Algorithms such as Logistic Regression, Random Forest, Naïve Bayes, KNN, Decision Trees, Support Vector, Ada Boost, Gradient Boosting, Extreme Gradient Boosting, Light Gradient Boosting, and Multi-Layer Perceptron Classifiers were chosen based on the specific problem. The models were trained on the training dataset and evaluated using the test dataset. To evaluate the performance of the prediction models, various metrics such as accuracy, precision, recall, F1-score, and ROC-AUC were utilized for classification tasks. Summarizing the findings and insights obtained from the analysis, we provided recommendations and actionable insights. These insights could be used for marketing strategies, product improvement, or customer retention initiatives.

This book was released on 2023-07-09 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this project, we embarked on a comprehensive journey of exploring the dataset and conducting analysis and predictions in the context of online retail. We began by examining the dataset and performing RFM (Recency, Frequency, Monetary Value) analysis, which allowed us to gain valuable insights into customer purchase behavior. Using the RFM analysis results, we applied K-means clustering, a popular unsupervised machine learning algorithm, to group customers into distinct clusters based on their RFM values. This clustering approach helped us identify different customer segments within the online retail dataset. After successfully clustering the customers, we proceeded to predict the clusters for new customer data. To achieve this, we trained various machine learning models, including logistic regression, support vector machines (SVM), K-nearest neighbors (KNN), decision trees, random forests, gradient boosting, naive Bayes, extreme gradient boosting, light gradient boosting, and multi-layer perceptron. These models were trained on the RFM features and the corresponding customer clusters. To evaluate the performance of the trained models, we employed a range of metrics such as accuracy, recall, precision, and F1 score. Additionally, we generated classification reports to gain a comprehensive understanding of the models' predictive capabilities. In order to provide a user-friendly and interactive experience, we developed a graphical user interface (GUI) using PyQt. The GUI allowed users to input customer information and obtain real-time predictions of the customer clusters using the trained machine learning models. This made it convenient for users to explore and analyze the clustering results. The GUI incorporated visualizations such as decision boundaries, which provided a clear representation of how the clusters were separated based on the RFM features. These visualizations enhanced the interpretation of the clustering results and facilitated better decision-making. To ensure the availability of the trained models for future use, we implemented model persistence by saving the trained models using the joblib library. This allowed us to load the models directly from the saved files without the need for retraining, thus saving time and resources. In addition to the real-time predictions, the GUI showcased performance evaluation metrics such as accuracy, recall, precision, and F1 score. This provided users with a comprehensive assessment of the model's performance and helped them gauge the reliability of the predictions. To delve deeper into the behavior and characteristics of the models, we conducted learning curve analysis, scalability analysis, and performance curve analysis. These analyses shed light on the models' learning capabilities, their performance with varying data sizes, and their overall effectiveness in making accurate predictions. The entire process from dataset exploration to RFM analysis, clustering, model training, GUI development, and real-time predictions was carried out seamlessly, leveraging the power of Python and its machine learning libraries. This approach allowed us to gain valuable insights into customer segmentation and predictive modeling in the online retail domain. By combining data analysis, clustering, machine learning, and GUI development, we were able to provide a comprehensive solution for online retail businesses seeking to understand their customers better and make data-driven decisions. The developed system offered an intuitive interface and accurate predictions, paving the way for enhanced customer segmentation and targeted marketing strategies. Overall, this project demonstrated the effectiveness of integrating machine learning techniques with graphical user interfaces to provide a user-friendly and interactive platform for analyzing and predicting customer clusters in the online retail industry.

PROJECT 2: DETECTING CYBERBULLYING TWEETS USING MACHINE LEARNING AND DEEP LEARNING WITH PYTHON GUI As social media usage becomes increasingly prevalent in every age group, a vast majority of citizens rely on this essential medium for day-to-day communication. Social media’s ubiquity means that cyberbullying can effectively impact anyone at any time or anywhere, and the relative anonymity of the internet makes such personal attacks more difficult to stop than traditional bullying. On April 15th, 2020, UNICEF issued a warning in response to the increased risk of cyberbullying during the COVID-19 pandemic due to widespread school closures, increased screen time, and decreased face-to-face social interaction. The statistics of cyberbullying are outright alarming: 36.5% of middle and high school students have felt cyberbullied and 87% have observed cyberbullying, with effects ranging from decreased academic performance to depression to suicidal thoughts. In light of all of this, this dataset contains more than 47000 tweets labelled according to the class of cyberbullying: Age; Ethnicity; Gender; Religion; Other type of cyberbullying; and Not cyberbullying. The data has been balanced in order to contain ~8000 of each class. The models used in this project are K-Nearest Neighbor, Random Forest, Naive Bayes, Logistic Regression, Decision Tree, Support Vector Machine, Adaboost, LGBM classifier, Gradient Boosting, XGB classifier, LSTM, and CNN. Three feature scaling used in machine learning are raw, minmax scaler, and standard scaler. Finally, you will develop a GUI using PyQt5 to plot cross validation score, predicted values versus true values, confusion matrix, learning curve, decision boundaries, performance of the model, scalability of the model, training loss, and training accuracy.
