Reasoning Scaffolding: Distilling the Flow of Thought from LLMs

Xiangyu Wen, Junhua Huang, Zeju Li +6

The prevailing approach to distilling reasoning from Large Language Models (LLMs)-behavioral cloning from textual rationales-is fundamentally limited. It teaches Small Language Mod…

Making Slow Thinking Faster: Compressing LLM Chain-of-Thought via Step Entropy

Zeju Li, Jianyuan Zhong, Ziyang Zheng +5

Large Language Models (LLMs) using Chain-of-Thought (CoT) prompting excel at complex reasoning but generate verbose thought processes with considerable redundancy, leading to incre…

Solve-Detect-Verify: Inference-Time Scaling with Flexible Generative Verifier

Jianyuan Zhong, Zeju Li, Zhijian Xu +3

Large Language Model (LLM) reasoning for complex tasks inherently involves a trade-off between solution accuracy and computational efficiency. The subsequent step of verification,…
