摘要
近期研究强调了注释熵对机器学习模型在LoRA微调过程中学习动态的影响。研究发现，当注释者对特定示例存在高度分歧时，模型往往会“忘记”这些有争议的实例，导致训练期间损失增加。这一现象在各种模型和数据集上均有一致观察，表明注释的质量和一致性在微调过程的有效性中起着关键作用。
Recent research has highlighted the impact of annotation entropy on the learning dynamics during LoRA fine-tuning in machine learning models. The study found that when there is high disagreement among annotators on specific examples, models tend to 'un-learn' those contested instances, leading to increased loss during training. This phenomenon was observed consistently across various models and datasets, suggesting that the quality and consistency of annotations play a crucial role in the effectiveness of fine-tuning processes.

Annotation Entropy Predicts Per-Example Learning Dynamics in LoRA Fine-TuningThe study reveals that LoRA fine-tuning leads to un-learning on contested examples, where high annotator disagreement results in increased loss during training. This pattern is consistent across multiple models and datasets, indicating a significant relationship between annotation entropy and learning dynamics.
