Multiplayer Nash Preference Optimization

ICLR 2026oral

Reinforcement learning from human feedback (RLHF) has emerged as the standard paradigm for aligning large language models (LLMs) with human preferences. However, reward-based methods built on the Bradley–Terry assumption struggle to capture the non-transitive and heterogeneous nature of real-world p…

PRISM-Physics: Causal DAG-Based Process Evaluation for Physics Reasoning

ICLR 2026poster

Benchmarks for competition-style reasoning have advanced evaluation in mathematics and programming, yet physics remains comparatively underexplored. Most existing physics benchmarks evaluate only final answers, which fail to capture reasoning processes, while recent stepwise methods rely on heuristi…

Web-CogReasoner: Towards Knowledge-Induced Cognitive Reasoning for Web Agents

ICLR 2026poster

Multimodal large-scale models have significantly advanced the development of web agents, enabling them to perceive and interact with the digital environment in a manner analogous to human cognition. In this paper, we argue that web agents must first acquire sufficient knowledge to engage in cognitiv…
