Federated bayesian personalized ranking

Webmodels for personalized ranking. The contributions of this work are: 1. We present the generic optimization criterion BPR-Opt derived from the maximum posterior estimator for optimal personalized ranking. We show the analogies of BPR-Opt to maximization of the area under ROC curve. 2. For maximizing BPR-Opt, we propose the WebDec 9, 2024 · 1) Bayesian Personalized Ranking (BPR): · BPR looks at the user, one item the user interacted with and one item the user did not (the unknown item).
