GRACE: Discriminator-Guided Chain-of-Thought Reasoning.
GRACE (Guiding chain-of-thought ReAsoning with a CorrectnEss Discriminator) is a stepwise decoding approach that steers the decoding process towards producing correct reasoning steps. It employs a step-level verifier or discriminator trained with a contrastive loss over correct and incorrect steps, which is used during decoding to score next-step candidates based on their correctness. This specific checkpoint serves as the generator model fine-tuned for reasoning tasks.
