Abstract: Retail recommendation systems are fundamental in the era of digital commerce, where consumer engagement, satisfaction, and revenue optimization depend on the relevance of product suggestions. With growing data complexity and user expectations, single-algorithm systems often fall short in delivering high-accuracy and adaptable solutions. This research introduces a comprehensive multi-algorithmic approach that evaluates and compares six powerful recommendation algorithms: Association Rule Mining (Apriori), Item-Based Collaborative Filtering, Content-Based Filtering, Market Basket Analysis, Cosine Similarity Heatmaps, and Network Graph Visualization. These algorithms were implemented and tested on the "Online Retail" dataset from the UCI Machine Learning Repository. We assess each model based on relevance, interpretability, scalability, and suitability for deployment in real-world e-commerce platforms. Additionally, the study integrates advanced visual tools to enhance interpretability and decision-making. The objective is to offer actionable insights into the strengths and limitations of each method and guide retail stakeholders and data practitioners in designing effective, customer-centric recommendation systems. Future extensions include integration of deep learning architectures and real-time personalization.
