LLMs can’t self-correct in reasoning tasks, DeepMind study finds - TechTalks

Oct 10, 2023 - news.bensbites.co
A study by Google DeepMind and the University of Illinois at Urbana-Champaign has found that large language models (LLMs) often struggle with self-correction without external feedback. The research suggests that self-correction, a technique where an LLM refines its own responses, can sometimes impair the performance of these models. The effectiveness of self-correction is not universal across all tasks and is largely contingent on the nature of the task at hand. In reasoning tasks, self-correction techniques typically succeed only when they can leverage external sources, such as human feedback, an external tool like a calculator or code executor, or a knowledge base.

The researchers tested self-correction on several benchmarks that measure model performance in solving math word problems, answering multiple-choice questions, and tackling question-answering problems that require reasoning. They found that self-correction works effectively when the models have access to the ground-truth labels included in the benchmark datasets. However, when the labels were removed from the self-correction process, the performance of the models began to decline significantly. The researchers conclude that self-correction should be approached with skepticism and applied judiciously.

Key takeaways:

  • A recent study by Google DeepMind and the University of Illinois at Urbana-Champaign reveals that large language models (LLMs) often falter when self-correcting their responses without external feedback, sometimes impairing their performance.
  • The success of self-correction is largely dependent on the nature of the task at hand and typically succeeds only when they can leverage external sources like human feedback or a knowledge base.
  • Self-correction can be effective in tasks such as modifying the style of the LLM’s output or making the response safer, referred to as 'post-hoc prompting', but may not enhance reasoning abilities.
  • The researchers conclude that it is crucial for the community to approach the concept of self-correction with skepticism and to apply it judiciously, recognizing its potential and its boundaries.
