Beyond Markovian: Reflective Exploration via Bayes-Adaptive RL for LLM Reasoning

ICLR 2026poster

Large Language Models (LLMs) trained via Reinforcement Learning (RL) have exhibited strong reasoning capabilities and emergent reflective behaviors, such as rethinking and error correction, as a form of in-context exploration. However, the Markovian policy obtained from conventional RL training does…

Chatbot Arena Estimate: towards a generalized performance benchmark for LLM capabilities

NAACL 2025industry

In industrial LLM development, evaluating large language models (LLMs) is critical for tasks like benchmarking internal models and detecting regressions during fine-tuning, but existing benchmark aggregation methods, such as Elo-based systems, can be resource-intensive, public facing, and time-consu…

Improving Multi-Agent Debate with Sparse Communication Topology

EMNLP 2024finding

Multi-agent debate has proven effective in improving large language models quality for reasoning and factuality tasks. While various role-playing strategies in multi-agent debates have been explored, in terms of the communication among agents, existing approaches adopt a brute force algorithm – each…
