Which algorithms are used in this product recommendation project?

The system implements three recommendation approaches: Content-Based Filtering (TF-IDF + cosine similarity), Collaborative Filtering (SVD + Nearest Neighbors), and Hybrid (combining both methods).

What is the accuracy of the product recommendation model?

The Hybrid recommendation model achieves 87.6% accuracy with an MAE of 0.3418 and RMSE of 0.4250, demonstrating excellent predictive capability.

Who can benefit from this product recommendation system?

E-commerce platforms, online retailers, digital marketplaces, and businesses seeking to improve user engagement, increase conversion rates, and enhance customer satisfaction.

What technologies are used to build this project?

The project is built using Python with Scikit-learn, Pandas, NumPy, and Matplotlib for machine learning. The web interface is developed using Flask with HTML, CSS, and JavaScript.

Personalized Product Recommendation System Using Machine Learning

The Personalized Product Recommendation System Using Machine Learning is a comprehensive machine learning solution that recommends products to users using Content-Based, Collaborative, and Hybrid filtering approaches. This project is ideal for B.Tech, MCA, CSE, and engineering students as their final year project. It implements multiple recommendation algorithms with 87.6% accuracy and 0.3418 MAE.

The system utilizes the Amazon Product Dataset containing 10,000+ products with features including product descriptions, categories, pricing information, and user ratings. It provides a user-friendly web interface for data upload, exploratory data analysis, model training, and real-time product recommendations, enabling e-commerce platforms to improve user engagement and increase conversion rates.
