WHALE: A Scalable Unified Model for Recommendation with Wukong-HSTU Architecture
The WHALE model unifies non-sequence and sequence feature modeling for recommendation systems by integrating Wukong and HSTU modules with an attention-based fusion mechanism. The architecture maintains both modules throughout the network, enabling high-order feature interactions to leverage detailed user behavior histories. WHALE demonstrates consistent improvements in offline experiments and delivers positive online gains in industrial settings, with deployment in production systems.
Why it matters: WHALE provides a practical and scalable approach to combining complementary recommendation architectures, showing real-world deployment and measurable improvements.
