  Customer Segmentation Using K-Means Clustering: A Machine Learning Approach for Market Strategy Optimization Abstract Customer segmentation is essential for businesses to tailor marketing strategies, personalize customer experiences, and optimize resource allocation. In this study, we apply the K-Means Clustering algorithm to segment customers based on their purchasing behavior, demographic information, and spending patterns. The K-Means algorithm, an unsupervised machine learning technique, efficiently grouped customers into distinct clusters. This study analyzes the results to identify key customer segments that businesses can target for personalized marketing. The effectiveness of the model is demonstrated through an analysis of clustering performance using metrics like silhouette score and visualizations of the customer segments. Introduction In today’s competitive market environment, businesses must understand customer behavior to tailor products and services that me...

  Big Mart Sales Prediction Using XGBoost Regressor: A Data-Driven Approach for Retail Analytics Abstract The accurate prediction of sales is essential for retail businesses to optimize inventory, pricing, and promotional strategies. This study implements an XGBoost Regressor model to predict the sales of products across various Big Mart stores using historical sales data. The model achieved an R-squared value of 0.6364 on the training data and 0.5867 on the test data. The results indicate that the XGBoost Regressor effectively captures patterns in the data, but further model optimization and additional features may enhance predictive accuracy. This paper outlines the methodology, experiments, and findings of the model’s application to retail sales forecasting. Introduction Sales forecasting is crucial for retail organizations to enhance decision-making, optimize resource allocation, and maximize profitability. Big Mart, a retail chain, is looking to predict the sales of pr...

  Medical Insurance Cost Prediction Using Linear Regression: A Comprehensive Data-Driven Approach Abstract The cost of medical insurance is influenced by various factors such as age, BMI, smoking status, and more. Accurate prediction of insurance costs can aid insurers in premium pricing and help individuals estimate their future healthcare expenses. This paper employs Linear Regression to model and predict medical insurance costs based on a dataset of patient information. The model achieved an R-squared value of 0.7515 on the training data and 0.7447 on the test data, demonstrating its capability to explain a significant proportion of the variance in insurance costs. The paper discusses the methodology, experimental results, and future improvements for enhanced prediction accuracy. Introduction In the healthcare industry, accurately predicting medical insurance costs is crucial for insurance companies to price premiums fairly and for individuals to make informed financial ...
