Tracing Agentic Failure from the Flow of Success

Samuel Yeh, Yiwen Zhu, Shaleen Deep +1

The paper introduces OAT, a lightweight unsupervised method that learns from successful LLM agent trajectories and detects error steps in failed runs by scoring deviations using ne…

Multi-Head Recurrent Memory Agents

Jiatong Li, Samuel Yeh, Sharon Li

Recurrent memory agents extend LLMs to arbitrarily long contexts by iteratively consolidating input into a fixed-size memory window. Despite their scalability, these agents exhibit…

Neglected Free Lunch from Post-training: Progress Advantage for LLM Agents

Changdae Oh, Wendi Li, Seongheon Park +3

Process reward models enable fine-grained, step-level evaluation of LLMs, yet building them for agentic settings remains prohibitively difficult: long-horizon interactions, irrever…

Hide-and-Seek in Trajectories: Discovering Failure Signals for VLA Runtime Monitoring

Seongheon Park, Wendi Li, Changdae Oh +4

Vision-Language-Action (VLA) models enable robots to follow natural language instructions and generalize across diverse tasks, but they remain vulnerable to execution failures that…

DECOR: Auditing LLM Deception via Information Manipulation Theory

Linyue Cai, Samuel Yeh, Jwala Dhamala +2

Large language models can deceive by subtly manipulating truthful information -- omitting key facts, shifting focus, or obscuring meaning -- making such behavior difficult to detec…

Uncertainty Quantification in LLM Agents: Foundations, Emerging Challenges, and Opportunities

Changdae Oh, Seongheon Park, To Eun Kim +8

Uncertainty quantification (UQ) for large language models (LLMs) is a key building block for safety guardrails of daily LLM applications. Yet, even as LLM agents are increasingly d…
