Scalable and Traceable Joint Uplift Modeling for Multi-Lever Online Marketing

A joint monotonic encoding layer is designed, which extends isotonic encoding to a joint space through linear interpolation and vector outer products, which allows the model to capture joint effects while ensuring strict joint monotonicity, aligning its output with economic common sense.

Can Generative Recommendation Reach Cold Items? A Temporal Perspective on Semantic-ID Generation

This work revisits SID-based generative recommendation under an absolute-time temporal protocol that separates seen and unseen targets and diagnoses the cold item reachability at the token level, and shows that SID generation is compositional but not fully open-ended.

TopoGR: Revealing and Preserving Latent Structure of Semantic ID in Generative Recommendation

TopoGR, a topology-preserving generative recommendation framework based on Bit-decomposable Semantic ID(Binary SID), is proposed and it is verified that the Hamming topology can capture item relatedness beyond exact SID matching.
