Teaching Large Language Models to Reason through Learning and Forgetting
Leveraging inference-time search in large language models has proven effective in further enhancing a trained model's capability to solve complex mathematical and reasoning problems. However, this app...

2️⃣ Learn successful reasoning paths ✅ while forgetting failed reasoning paths ❌ at the same time, which we call Unlikelihood Fine-Tuning (UFT) 3️⃣ Small learning rate is crucial to preserve inference-time search capabilities

1️⃣ Aggregate reasoning paths from diverse sources: Chain-of-Thought, inference-time search (Tree-of-Thought, Reasoning-via-Planning), classic algorithms (BFS, DFS)

Can we make LLMs reason effectively without a huge inference time cost? We show a powerful approach through learning and forgetting! Our recipe: ⬇️
