做持续学习和模型终身优化的研究者值得关注——它用“睡眠”机制解决了LLM记忆遗忘问题，比传统微调更接近人类学习方式，看完会有启发。
受人类学习过程启发，研究者提出了一种名为“睡眠”的范式，让大语言模型能够持续学习，将短期脆弱记忆蒸馏为稳定的长期知识。该范式包含两个阶段：记忆巩固（通过知识播种将小模型记忆蒸馏到大模型）和梦境（模型通过强化学习生成合成数据自我改进）。实验证明，该方法在长时任务、持续学习、知识整合和少样本泛化上效果显著。这项工作解决了LLM无法持续更新长期参数的核心痛点，为模型终身学习提供了新思路。
Language Models Need Sleep: Learning to Self-Modify and Consolidate Memories
The past few decades have witnessed significant advances in the design of machine learning algorithms, from early studies on task-specific shallow models to more general deep Large Language Models (LLMs). Despite showing promising results in tasks that require instant prediction or in-context learning, existing models lack the ability to continually learn and effectively transfer their temporal in-context knowledge to their long-term parameters. Inspired by human learning process, we introduce a ''Sleep'' paradigm that allows the models to continually learn, distill their short-term fragile memories into stable long-term knowledge with replay, and recursively improve themselves with ''Dreaming'' process. In more detail, sleep consists of two stages: (1) Memory Consolidation: an upward distillation process, called Knowledge Seeding, where the memories of a smaller-self are distilled into a larger network to provide more capacity while preserving the knowledge. As a proof of concept, we present a new Generalized Distillation process for {Knowledge Seeding} (i.e., the combination of on-policy distillation with Reinforcement Learning (RL)-based imitation learning); (2) Dreaming: a self-improvement phase, where the model uses RL to generate a curriculum of synthetic data to rehearse new knowledge and refine existing capabilities without human supervision. Our experiments on long-horizon, continual learning, knowledge incorporation, and few-shot generalization tasks support the importance of the sleep stage.
