Localizing Emergent Failures in Agentic AI: Recovering Minimal Repair Families via Counterfactual Replay

Bingjie Li, Yumeng Song, Zhongming Yao +1

Failures in agentic AI systems can arise from interactions among messages exchanged by multiple large language model (LLM) agents. Pointwise attribution cannot distinguish a jointl…

Robustness Analysis of Agentic AI to Inconsistent and Incomplete Tool Responses

Jiachen Xu, Torben Bach Pedersen, Zhongming Yao +2

Tool-using agents increasingly rely on external tools to complete multi-step tasks, but tool returns can fail in different ways and require different recovery actions. Existing rob…

VeriTS: Verifiable Model-Enhanced Time-Series Queries on Blockchain Systems

Zhongming Yao, Jun Pang, Chenxu Wang +3

Every blockchain transaction carries a timestamp, and the chain imposes a total order. On-chain data therefore forms per-source time-series streams. However, existing systems suppo…

A-CPES: A Reference Framework for Agentic AI in Cyber-Physical Energy Systems

Xiaoyu Zhang, Qiuye Sun, Jiachen Xu +2

Energy system operation contains a loop of work that automation has never taken over: posing the optimization problem the current cycle should solve, disposing of infeasibility, se…

Replacing Multi-Step Assembly of Data Preparation Pipelines with One-Step LLM Pipeline Generation for Table QA

Fengyu Li, Junhao Zhu, Kaishi Song +4

Table Question Answering (TQA) aims to answer natural language questions over structured tables. Large Language Models (LLMs) enable promising solutions to this problem, with opera…
