Sharpness-aware Model Merging with Salience Recovery for LLM-based Cross-Domain Sequential Recommendation

Huwei Ji, Jiajie Su, Yuyuan Li +2

LLM-based Cross-Domain Sequential Recommendation (CDSR) leverages LLMs to enhance target performance via deep semantic reasoning, alleviating the dependency on overlapping users. A…

Enhancing Attributed Graph Networks with Alignment and Uniformity Constraints for Session-based Recommendation

Xinping Zhao, Chaochao Chen, Jiajie Su +2

Session-based Recommendation (SBR), seeking to predict a user's next action based on an anonymous session, has drawn increasing attention for its practicability. Most SBR models on…
