Welcome to the NCF Recommender System with PyTorch! In this project, An end-to-end Recommender System using an adjusted version of Neural Collaborative Filtering (NCF) with PyTorch. the model is trained on the MovieLens-1M dataset 🎥, served using FastAPI, hosted on Streamlit 🚀.

• Notebook: NCF Recommender System with PyTorch: A Deep Dive

• Our adjusted architecture of NCF enables the input of the user/item features besides the user/item IDs.

• Quick Reminder: A recommender system is not just a ranking model, but a pipeline consisting of: Items Retrieval, Filtering, Ranking, and Ordering. (Detailed explanation in the notebook)
