Tracking the Truth: Object-Centric Spatio-Temporal Monitoring for Video Large Language Models

Tri Cao, Khoi Le, Thong Nguyen +7

While multimodal large language models (MLLMs) have advanced video understanding, they remain highly prone to hallucinations in dynamic scenes. We argue this stems from a failure i…

VerificAgent: Domain-Specific Memory Verification for Scalable Oversight of Aligned Computer-Use Agents

Thong Q. Nguyen, Shubhang Desai, Raja Hasnain Anwar +3

Continual memory augmentation lets computer-using agents (CUAs) learn from prior interactions, but unvetted memories can encode domain-inappropriate or unsafe heuristics--spurious…
