ASCon: A Direction-Aware Reciprocal Agent--Step Contextualization Model for Failure Attribution in Multi-Agent Systems

Shuyu Jiang, Yue Ran, Kaiyu Xu +5

Failure attribution in LLM-based multi-agent systems (MAS) aims to answer who caused failures, when they occurred, and why by identifying responsible targets including faulty agent…

UGID: Unified Graph Isomorphism for Debiasing Large Language Models

Zikang Ding, Junchi Yao, Junhao Li +4

Large language models (LLMs) exhibit pronounced social biases. Output-level or data-optimization--based debiasing methods cannot fully resolve these biases, and many prior works ha…

Transfer Learning for Contextual Joint Assortment-Pricing under Cross-Market Heterogeneity

Elynn Chen, Xi Chen, Yi Zhang

We study transfer learning for contextual joint assortment-pricing under a multinomial logit choice model with bandit feedback. A seller operates across multiple related markets an…
