A new research paper explores the effectiveness of using majority-vote rewards in reinforcement learning, finding that they can closely track verifiable rewards even with a high error rate. The study argues that the key lies in batch-level updates rather than prompt-level analysis, as shared parameters mean individual prompt gradients are minimal. The research demonstrates that majority-vote errors are incoherent across prompts, preserving the update direction similar to gold-standard rewards, and this equivalence holds across model checkpoints.

IMPACT Suggests that self-generated labels can be effective in training AI models, potentially reducing the need for extensive human verification.
