Machine Unlearning: Linear Filtration for Logit-based Classifiers

Baumhauer, Thomas, Schöttle, Pascal, Zeppelzauer, Matthias

Understand

Recently enacted legislation grants individuals certain rights to decide in what fashion their personal data may be used, and in particular a "right to be forgotten".

  • This poses a challenge to machine learning: how to proceed when an individual retracts permission to use data which has been part of the training process of a model? From this question emerges the field of machine unlearning, which could be broadly described as the investigation of how to "delete training data from models".
  • Our work complements this direction of research for the specific setting of class-wide deletion requests for classification models (e.g.
  • deep neural networks).
