CoT 思维链与分步推导

🎯Core Definition

Chain-of-Thought (CoT) Prompting is a paradigm that elicits intermediate reasoning steps from an LLM before producing the final answer; variants include Zero-shot CoT (appending `Let's think step by step`), Few-shot CoT (supplying step-by-step human derivations in exemplars), Least-to-Most Prompting (solving sub-problems iteratively), and Auto-CoT; it allocates dynamic autoregressive computation budget across Transformer layers to compute and store intermediate state representations.

💡Use Cases

Multi-step mathematical reasoning (GSM8K, MATH), complex algorithmic code generation, enterprise rule evaluation, and causal deduction.

⚡Key Problems Solved

Direct answering forces the model to jump directly to final predictions within a single forward pass, collapsing on complex multi-variable reasoning; CoT breaks reasoning into sequential verbalized tokens, slashing cognitive leap errors.
