If an LLM Were a Character, Would It Know Its Own Story? Evaluating Lifelong Learning in LLMs

Siqi Fan, Xiusheng Huang, Yiqun Yao +6

Large language models (LLMs) can carry out human-like dialogue, but unlike humans, they are stateless due to the superposition property. However, during multi-turn, multi-agent int…

Hesitation and Tolerance in Recommender Systems

Kuan Zou, Aixin Sun, Yitong Ji +5

Users' interactions with recommender systems often involve more than simple acceptance or rejection. We highlight two overlooked states: hesitation, when people deliberate without…

OneTrans: Unified Feature Interaction and Sequence Modeling with One Transformer in Industrial Recommender

Zhaoqi Zhang, Haolei Pei, Jun Guo +5

In recommendation systems, scaling up feature-interaction modules (e.g., Wukong, RankMixer) or user-behavior sequence modules (e.g., LONGER) has achieved notable success. However,…

Error Analyses of Auto-Regressive Video Diffusion Models: A Unified Framework

Jing Wang, Fengzhuo Zhang, Xiaoli Li +5

Auto-Regressive Video Diffusion Models (AR-VDMs) have shown strong capabilities in generating long, photorealistic videos, but suffer from two key limitations: (i) history forgetti…

Event Extraction in Large Language Model

Bobo Li, Xudong Han, Jiang Liu +11

Large language models (LLMs) and multimodal LLMs are changing event extraction (EE): prompting and generation can often produce structured outputs in zero shot or few shot settings…

The Price of a Second Thought: On the Evaluation of Reasoning Efficiency in Large Language Models

Siqi Fan, Bowen Qin, Peng Han +3

Recent thinking models trained with reinforcement learning and backward-checking CoT often suffer from overthinking: they produce excessively long outputs even on simple problems,…
