Teaching LLMs to Self-Evolve: Cultivating Core Meta-Skills with Reinforcement Learning

Shujin Wu, Cheng Qian, Xiusi Chen +1

Test-time scaling through iterative self-evolution with environment feedback, as demonstrated by AlphaEvolve, shows remarkable performance gains. We hypothesize that the success of…

PEARL: Self-Evolving Assistant for Time Management with Reinforcement Learning

Bingxuan Li, Jeonghwan Kim, Cheng Qian +4

Overlapping calendar invitations force busy professionals to repeatedly decide which meetings to attend, reschedule, or decline. We refer to this preference-driven decision process…

MemGuard: Preventing Memory Contamination in Long-Term Memory-Augmented Large Language Models

Hyeonjeong Ha, Jeonghwan Kim, Cheng Qian +7

Memory-augmented large language models extend reasoning beyond a fixed context window by maintaining long-term memory across interactions. However, existing memory systems often co…

MolLingo: Molecule-Native Representations for LLM-Powered Scientific Agents

Thao Nguyen, Heng Ji

We present MolLingo, a multi-agent system that emulates the reasoning process of a chemist to automate molecular design. Existing LLM-based approaches either operate as standalone…

UserHarness: Harnessing User Minds for Stronger Agent Theory-of-Mind

Cheng Qian, Jiayu Liu, Heng Ji

Understanding what a user believes and intends is central to building effective agent assistants. This ability is often evaluated through Theory-of-Mind (ToM) tasks, where success…

Decoding the Critique Mechanism in Large Reasoning Models

Hoang Phan, Quang H. Nguyen, Hung T. Q. Le +3

Large Reasoning Models (LRMs) exhibit backtracking and self-verification mechanisms that enable them to revise intermediate steps and reach correct solutions, yielding strong perfo…
