On the Effectiveness of Unlearning in Session-Based Recommendation

Xin Xin, Liu Yang, Ziqi Zhao +4

Session-based recommendation predicts users' future interests from previous interactions in a session. Despite the memorizing of historical samples, the request of unlearning, i.e.…

Debiasing Sequential Recommenders through Distributionally Robust Optimization over System Exposure

Jiyuan Yang, Yue Ding, Yidan Wang +7

Sequential recommendation (SR) models are typically trained on user-item interactions which are affected by the system exposure bias, leading to the user preference learned from th…

Multi-Defendant Legal Judgment Prediction via Hierarchical Reasoning

Yougang Lyu, Jitai Hao, Zihan Wang +6

Multiple defendants in a criminal fact description generally exhibit complex interactions, and cannot be well handled by existing Legal Judgment Prediction (LJP) methods which focu…

Instruction Distillation Makes Large Language Models Efficient Zero-shot Rankers

Weiwei Sun, Zheng Chen, Xinyu Ma +6

Recent studies have demonstrated the great potential of Large Language Models (LLMs) serving as zero-shot relevance rankers. The typical approach involves making comparisons betwee…

Generalizing Few-Shot Named Entity Recognizers to Unseen Domains with Type-Related Features

Zihan Wang, Ziqi Zhao, Zhumin Chen +3

Few-shot named entity recognition (NER) has shown remarkable progress in identifying entities in low-resource domains. However, few-shot NER methods still struggle with out-of-doma…
