Bad Seeing or Bad Thinking? Rewarding Perception for Multimodal Reasoning

ICML 2026oral

Achieving robust perception-reasoning synergy is a central goal for advanced Vision-Language Models (VLMs). Recent advancements have pursued this goal via architectural designs or agentic workflows. However, these approaches are often limited by static textual reasoning or complicated by the signifi…

Emergent Hierarchical Reasoning in LLMs through Reinforcement Learning

ICLR 2026poster

Reinforcement Learning (RL) has proven highly effective at enhancing the complex reasoning abilities of Large Language Models (LLMs), yet underlying mechanisms driving this success remain largely opaque. Our analysis reveals that puzzling phenomena like ``aha moments", ``length-scaling'' and entropy…

Reverse-Engineered Reasoning for Open-Ended Generation

ICLR 2026poster

While the "deep reasoning" paradigm has spurred significant advances in verifiable domains like mathematics, its application to open-ended, creative generation remains a critical challenge. The two dominant methods for instilling reasoning—reinforcement learning (RL) and instruction distillation --…
