English(EN) No Model Required: Text Entropy Rate Filtering Mitigates Iterative Fine-Tuning Collapse

新信息论方法对抗人工智能模型崩溃

研究人员开发了一种新颖的方法来对抗语言模型迭代微调中的“模型崩溃”现象,即输出多样性随时间减少。这种基于信息论并利用 Kontoyiannis 熵率估计器的新方法,不需要访问模型对数概率或真实人类数据。在 Llama-3.1-8B 的实验中,这种基于文本的过滤技术显著提高了文本多样性指标,其性能优于依赖模型访问的既有方法。 AI

影响 为改进 LLM 微调中使用的合成数据的多样性和质量提供了一种新的、与模型无关的方法。

    无需模型:文本熵率过滤可缓解迭代微调崩溃

    arXiv:2610.01493v1 Announce Type: cross Abstract: Iterative fine-tuning on synthetic data causes \emph{model collapse}: output diversity narrows as rare patterns are progressively lost, a signature most visible as phrase-level repetition. Existing mitigations either require model…
