Fidelity-Aware Recommendation Explanations via Stochastic Path Integration

Oren Barkan, Yahlly Schein, Yehonatan Elisha +3

Explanation fidelity, which measures how accurately an explanation reflects a model's true reasoning, remains critically underexplored in recommender systems. We introduce SPINRec…

Extracting Interaction-Aware Monosemantic Concepts in Recommender Systems

Dor Arviv, Yehonatan Elisha, Oren Barkan +1

We present a method for extracting \emph{monosemantic} neurons, defined as latent dimensions that align with coherent and interpretable concepts, from user and item embeddings in r…

Explainable Recommendations via Attentive Multi-Persona Collaborative Filtering

Oren Barkan, Yonatan Fuchs, Avi Caciularu +1

Two main challenges in recommender systems are modeling users with heterogeneous taste, and providing explainable recommendations. In this paper, we propose the neural Attentive Mu…

Attentive Item2Vec: Neural Attentive User Representations

Oren Barkan, Avi Caciularu, Ori Katz +1

Factorization methods for recommender systems tend to represent users as a single latent vector. However, user behavior and interests may change in the context of the recommendatio…
