Enhanced Generative Recommendation via Content and Collaboration Integration

no code implementations27 Mar 2024 Yidan Wang, Zhaochun Ren, Weiwei Sun, Jiyuan Yang, Zhixiang Liang, Xin Chen, Ruobing Xie, Su Yan, Xu Zhang, Pengjie Ren, Zhumin Chen, Xin Xin

However, existing generative recommendation approaches still encounter challenges in (i) effectively integrating user-item collaborative signals and item content information within a unified generative framework, and (ii) executing an efficient alignment between content information and collaborative signals.

Uncovering Selective State Space Model's Capabilities in Lifelong Sequential Recommendation

1 code implementation25 Mar 2024 Jiyuan Yang, Yuanzi Li, Jingyu Zhao, Hanbing Wang, Muyang Ma, Jun Ma, Zhaochun Ren, Mengqi Zhang, Xin Xin, Zhumin Chen, Pengjie Ren

We conduct extensive experiments to evaluate the performance of representative sequential recommendation models in the setting of lifelong sequences.

Debiasing Sequential Recommenders through Distributionally Robust Optimization over System Exposure

1 code implementation12 Dec 2023 Jiyuan Yang, Yue Ding, Yidan Wang, Pengjie Ren, Zhumin Chen, Fei Cai, Jun Ma, Rui Zhang, Zhaochun Ren, Xin Xin

Then, we introduce a penalty to items with high exposure probability to avoid the overestimation of user preference for biased samples.

On the User Behavior Leakage from Recommender System Exposure

1 code implementation16 Oct 2022 Xin Xin, Jiyuan Yang, Hanbing Wang, Jun Ma, Pengjie Ren, Hengliang Luo, Xinlei Shi, Zhumin Chen, Zhaochun Ren

Given the fact that system exposure data could be widely accessed from a relatively larger scope, we believe that the user past behavior privacy has a high risk of leakage in recommender systems.
