DiffCoT: Diffusion-styled Chain-of-Thought Reasoning in LLMs (2026.findings-acl)
Copied to clipboard
| Challenge: | Chain-of-Thought (CoT) reasoning improves multi-step mathematical problem solving in large language models but is vulnerable to exposure bias and error accumulation. |
| Approach: | They propose a diffusion-styled CoT framework that reformulates CoT reasoning as an iterative denoising process. |
| Outcome: | The proposed framework outperforms existing methods on three multi-step CoT reasoning benchmarks. |
