DPGR: Dual-Domain Spatiotemporal Generative Retrieval for Intent-Aware Local Life Service Recommendation
DPGR (Dual-domain Spatiotemporal Generative Retrieval), a unified dual-domain generative retrieval framework for LLSR, introduces a Spatiotemporal State-Conditioned Token Modeling mechanism that injects dynamic user context into multiple stages of the encoder, enabling state-dependent reweighting and adaptive preferenc...
