Summary

The survey examines Large Language Models (LLMs) for "slow thinking," categorizing methods into test-time scaling, reinforced learning, and slow-thinking frameworks. It aims to merge human-like deep thinking with scalable efficiency for reasoning, synthesizing insights from over 100 studies. Key areas include integrating supervision, using reinforcement learning for tasks like medical reasoning, and categorizing reward models. Recent research focuses on speculative decoding, scalable oversight, reinforcement learning with large language models, visual reasoning, transfer learning in network biology, open foundation language models, and solving math word problems with feedback. Contributions also address safety in deep learning, multimodal reasoning, and improving model stability and adaptability in computer vision tasks.
