Overview

• Chain of Thought (CoT) prompting significantly improves language model performance on reasoning tasks
• Study examines why CoT works using linear regression as a test case
• Transformers with CoT can learn multi-step gradient descent while regular transformers cannot
• CoT enables models to recover ground-truth weight vectors and generalize to unseen data
• Looped transformers with CoT show substantially better performance than standard transformers

Plain English Explanation

Why does asking AI to "think step by step" make it perform better? That's the question this research tackles.

Chain of Thought prompting is when you ask a language model to solve a pro...
