UxSID: Semantic-Aware User Interests Modeling for Ultra-Long Sequence
UxSID is a new machine learning framework that models long user behavior sequences using semantic grouping and dual-level attention, achieving state-of-the-art performance with a 0.337% revenue lift in large-scale advertising tests. The approach balances computational efficiency with semantic awareness by using Semantic IDs rather than item-specific search methods.
