From Outcomes to Actions: Leveraging Hindsight for Long-Horizon Language Agent Training

ICML 2026poster

Reinforcement learning (RL) has become a widely adopted technique for improving large language models (LLMs) on complex tasks. Despite this progress, existing RL methods still face challenges in training agents with longer-horizon interactions. One major bottleneck is distinguishing the contribution…

Data-Efficient Selection via Grammatical Complexity in Continual Pre-training of Domain-Specific LLMs

EMNLP 2025

Data efficiency is crucial in domain-specific continual pre-training (CPT) of large language models (LLMs), especially under resource constraints. Aiming for “small data, big impact,” this work addresses the limitations of existing domain-specific data selection strategies, which often rely on scarc

From Remembering to Metacognition: Do Existing Benchmarks Accurately Evaluate LLMs?

EMNLP 2025

Despite the rapid development of large language models (LLMs), existing benchmark datasets often focus on low-level cognitive tasks, such as factual recall and basic comprehension, while providing limited coverage of higher-level reasoning skills, including analysis, evaluation, and creation. In thi

Think Thrice Before You Act: Progressive Thought Refinement in Large Language Models

ICLR 2025poster

Recent advancements in large language models (LLMs) have demonstrated that progressive refinement, rather than providing a single answer, results in more accurate and thoughtful outputs. However, existing methods often rely heavily on supervision signals to evaluate previous responses, making it…
