New rewards encourage AI reasoning reliance, but accuracy trade-offs emerge

Researchers have developed four new reward mechanisms to encourage language models to rely more on their generated reasoning processes. These methods, including gradient sensitivity and confidence gaps, were tested on instruction-tuned models using benchmarks like GSM8K and StrategyQA. While some configurations improved the models' reliance on reasoning edits, the effects on overall accuracy and robustness varied, with some settings leading to answer copying. AI

IMPACT Introduces novel reward mechanisms to enhance AI's reliance on its reasoning, potentially improving trustworthiness in complex tasks.

    Chain of Faith: Policy-Internal Rewards for Reasoning Reliance

    Chain-of-thought (CoT) explanations can sound plausible while having little influence on a model's final answer. We study four rewards that use the policy's own signals to encourage reliance on generated reasoning: gradient sensitivity, confidence gaps, progressive confidence gai…
