arXiv:2510.17917v2 Announce Type: replace Abstract: Data unlearning aims to remove the influence of specific training samples from a trained model. In fine-tuning methods, data unlearning relies primarily on loss maximization over forget samples, which often leads to quality degradation or incomplete forgetting. Existing methods perform unlearning uniformly across diffusion stages, ignoring diffusion dynamics from noise to data. Our systematic study of diffusion phases shows that forgetting in diffusion models is uneven across time and frequency, with theoretical justification of distributive
The increasing focus on data privacy, copyright, and regulatory compliance is driving the need for effective methods to remove specific data influences from AI models, particularly as models become more pervasive and powerful.
This research offers a more nuanced and potentially efficient approach to 'unlearning' data in complex AI models, which is critical for legal compliance, ethical AI development, and model refinement without complete retraining.
Current methods of data unlearning, which often lead to quality degradation or incomplete forgetting, are challenged by this new approach that recognizes the unevenness of forgetting across diffusion stages.
