Query: Mixture-of-tastes Models for Representing Users with Diverse Interests   Most existing recommendation approaches implicitly treat user tastes as
unimodal, resulting in an average-of-tastes representations when multiple
distinct interests are present. We show that appropriately modelling the
multi-faceted nature of user tastes through a mixture-of-tastes model leads to
large increases in recommendation quality. Our result holds both for deep
sequence-based and traditional factorization models, and is robust to careful
selection and tuning of baseline models. In sequence-based models, this
improvement is achieved at a very modest cost in model complexity, making
mixture-of-tastes models a straightforward improvement on existing baselines.
