IdleSpec: Exploiting Idle Time via Speculative Planning for LLM Agents

Daewon Choi, Kyunghyun Park, Woomin Song +4

Large language model (LLM)-based agents solve complex tasks by leveraging multi-step reasoning with iterative tool calls and environment interactions, which incur idle time while w…

ExComm: Exploration-Stage Communication for Error-Resilient Agentic Test-Time Scaling

Woomin Song, Beomjun Kim, Daewon Choi +4

A common failure mode in long-horizon agentic test-time scaling is error propagation, where factual errors or invalid deductions introduced at intermediate steps persist in the age…

HAMLET: Switch your Vision-Language-Action Model into a History-Aware Policy

Myungkyu Koo, Daewon Choi, Taeyoung Kim +4

Inherently, robotic manipulation tasks are history-dependent: leveraging past context could be beneficial. However, most existing Vision-Language-Action models (VLAs) have been des…
