Modeling High-order Interactions across Multi-interests for Micro-video Reommendation (Student Abstract)

Personalized recommendation system has become pervasive in various video platform. Many effective methods have been proposed, but most of them didn't capture the user's multilevel interest trait and dependencies between their viewed micro-videos well. To solve these problems, we propose a Self-over-Co Attention module to enhance user's interest representation. In particular, we first use co-attention to model correlation patterns across different levels and then use selfattention to model correlation patterns within a specific level. Experimental results on filtered public datasets verify that our presented module is useful.
