IcFuzz: Fuzzing Isaac Sim with Semantic Stage Guidance and Multi-level Mutation
Zhixiang Chen, Zhuangbin Chen, Ruoxi Jia +4
Robotics simulators serve as a foundational infrastructure for embodied AI, facilitating safe and scalable robotic system development. NVIDIA Isaac Sim has emerged as one of the mo…
LogNLQ: Natural-Language Log Querying with Parser-Induced and Semantically Grounded Schemas
Juepeng Wang, Jinyang Liu, Zhuangbin Chen +1
Logs are essential for system monitoring and failure diagnoses in modern software systems, yet querying them through natural language remains an open challenge. Existing approaches…
MASPrism: Lightweight Failure Attribution for Multi-Agent Systems Using Prefill-Stage Signals
Yang Liu, Hongjiang Feng, Junsong Pu +1
Failure attribution in LLM-based multi-agent systems aims to identify the steps that contribute to a failed execution. This task remains difficult because a single execution can co…
TypeScript Repository Indexing for Code Agent Retrieval
Junsong Pu, Yichen Li, Zhuangbin Chen
Graph-based code indexing can improve context retrieval for LLM-based code agents by preserving call chains and dependency relationships that keyword search and similarity retrieva…
MAS-FIRE: Fault Injection and Reliability Evaluation for LLM-Based Multi-Agent Systems
Jin Jia, Zhiling Deng, Zhuangbin Chen +2
As LLM-based Multi-Agent Systems (MAS) are increasingly deployed for complex tasks, ensuring their reliability has become a pressing challenge. Since MAS coordinate through unstruc…
LogPrism: Unifying Structure and Variable Encoding for Effective Log Compression
Yang Liu, Kaiming Zhang, Zhuangbin Chen +1
In the field of log compression, the prevailing "parse-then-compress" paradigm fundamentally limits effectiveness by treating log parsing and compression as isolated objectives. Wh…
