Learning from Mistakes: Negative Reasoning Samples Enhance Out-of-Domain Generalization

Xueyun Tian, Minghua Ma, Bingbing Xu +6

Supervised fine-tuning (SFT) on chain-of-thought (CoT) trajectories demonstrations is a common approach for enabling reasoning in large language models. Standard practices typicall…
