Subtract the Corruption: Training-Data-Free Corrective Machine Unlearning using Task Arithmetic

arXiv — stat.MLTuesday, November 25, 2025 at 5:00:00 AM
  • A new approach to Corrective Machine Unlearning (CMU) has been introduced, focusing on a source-free method that allows for the removal of corrupted training data without needing access to the original dataset. This method, termed Corrective Unlearning in Task Space (CUTS), utilizes a small proxy set of corrupted samples to guide the unlearning process through task arithmetic principles.
  • This development is significant as it addresses a common challenge in machine learning where corrupted data can adversely affect model performance. By enabling unlearning without the original data, CUTS enhances the flexibility and applicability of machine learning models in real-world scenarios where data access may be restricted.
  • The emergence of methods like CUTS reflects a growing trend in artificial intelligence to improve data handling and model adaptability. As machine learning applications expand, the need for effective unlearning techniques becomes increasingly critical, paralleling advancements in related fields such as computer vision and multimodal representation learning, which also seek to refine model training and performance.
