Three recommendation models — trained on real purchase ratings — compete to guess what a shopper hasn't rated yet. Below: the leaderboard, the models, and live predictions per user.
Lower RMSE means predicted ratings land closer to what users actually gave. Precision/Recall/F1 measured at k=10.
No personalization here — just what the crowd actually loved.
Predictions from the SVD model, for products this user hasn't rated yet.
