arXiv:2602.05395v2 Announce Type: replace-cross Abstract: A simple strategy for improving LLM accuracy, especially in math and reasoning problems, is to sample multiple responses and submit the answer most consistently reached. In this paper we leverage Bayesian prior information to save on sampling costs, stopping once sufficient consistency is reached. Although the exact posterior is computationally intractable, we further introduce an efficient "L-aggregated" stopping policy that tracks only the L-1 most frequent answer counts. Theoretically, we prove that L=3 is all you need: this coarse a
The paper leverages Bayesian methods to address the current challenge of improving LLM accuracy, particularly in reasoning tasks, by optimizing repeated sampling strategies.
This development offers a more efficient methodology for improving LLM reliability, which is crucial for their broader adoption in applications requiring high accuracy, reducing operational costs and computational waste.
Current methods for enhancing LLM answer consistency often involve costly multiple samples; this research introduces a more efficient 'L-aggregated' stopping policy that significantly reduces sampling costs.
