Leveraging Memory Retrieval to Enhance LLM-based Generative Recommendation

no code implementations23 Dec 2024 Chengbing Wang, Yang Zhang, Fengbin Zhu, Jizhi Zhang, Tianhao Shi, Fuli Feng

Leveraging Large Language Models (LLMs) to harness user-item interaction histories for item generation has emerged as a promising paradigm in generative recommendation.

Fair Recommendations with Limited Sensitive Attributes: A Distributionally Robust Optimization Approach

1 code implementation2 May 2024 Tianhao Shi, Yang Zhang, Jizhi Zhang, Fuli Feng, Xiangnan He

To this end, we propose Distributionally Robust Fair Optimization (DRFO), which minimizes the worst-case unfairness over all potential probability distributions of missing sensitive attributes instead of the reconstructed one to account for the impact of the reconstruction errors.

SphereHead: Stable 3D Full-head Synthesis with Spherical Tri-plane Representation

no code implementations8 Apr 2024 Heyuan Li, Ce Chen, Tianhao Shi, Yuda Qiu, Sizhe An, GuanYing Chen, Xiaoguang Han

We further introduce a view-image consistency loss for the discriminator to emphasize the correspondence of the camera parameters and the images.

Preliminary Study on Incremental Learning for Large Language Model-based Recommender Systems

1 code implementation25 Dec 2023 Tianhao Shi, Yang Zhang, Zhijian Xu, Chong Chen, Fuli Feng, Xiangnan He, Qi Tian

Instead of dismissing the role of incremental learning, we attribute the lack of anticipated performance enhancement to a mismatch between the LLM4Rec architecture and incremental learning: LLM4Rec employs a single adaptation module for learning recommendations, limiting its ability to simultaneously capture long-term and short-term user preferences in the incremental learning context.

Reformulating CTR Prediction: Learning Invariant Feature Interactions for Recommendation

1 code implementation26 Apr 2023 Yang Zhang, Tianhao Shi, Fuli Feng, Wenjie Wang, Dingxian Wang, Xiangnan He, Yongdong Zhang

However, such a manner inevitably learns unstable feature interactions, i. e., the ones that exhibit strong correlations in historical data but generalize poorly for future serving.
