PEGA: Personality-Guided Preference Aggregator for Ephemeral Group Recommendation

no code implementations18 Apr 2023 Guangze Ye, Wen Wu, Liye Shi, Wenxin Hu, Xin Chen, Liang He

The role of personality in our approach is twofold: (1) To estimate individual users' importance in a group and provide explainability; (2) to alleviate the data sparsity issue that occurred in ephemeral groups.

Self-Attentive Sequential Recommendation with Cheap Causal Convolutions

no code implementations2 Nov 2022 Jiayi Chen, Wen Wu, Liye Shi, Yu Ji, Wenxin Hu, Xi Chen, Wei Zheng, Liang He

We evaluate the effectiveness of the proposed model in terms of both accurate and calibrated sequential recommendation.

A Unified Positive-Unlabeled Learning Framework for Document-Level Relation Extraction with Different Levels of Labeling

1 code implementation17 Oct 2022 Ye Wang, Xinxin Liu, Wenxin Hu, Tao Zhang

To solve the common incomplete labeling problem, we propose a unified positive-unlabeled learning framework - shift and squared ranking loss positive-unlabeled (SSR-PU) learning.
