Book Recommendation System (SVD++ & BPR)

This project is a Machine Learning-based Book Recommendation System that provides personalized book recommendations to users using two collaborative filtering algorithms:

• SVD++ (Singular Value Decomposition++) → trained on explicit feedback (ratings)
• BPR (Bayesian Personalized Ranking) → trained on implicit feedback (user-book interactions)

The system is built with Flask, and includes APIs for training, evaluation, and generating recommendations.
