Effective Reasoning Chains Reduce Intrinsic Dimensionality
Researchers demonstrate that effective chain-of-thought reasoning reduces intrinsic dimensionality—the minimum number of model dimensions needed to achieve target accuracy—offering a quantifiable metric for understanding why reasoning strategies improve language model generalization. Testing on GSM8K with Gemma models reveals strong inverse correlation between lower intrinsic dimensionality and better performance on both in-distribution and out-of-distribution tasks.
