Project: Machine Unlearning Algorithms for Data Removal

Supervisor: Dr. Rahul Krishnan

Description:

I worked with Dr. Rahul Krishnan on the development of new machine unlearning techniques for data removal.

We considered the problem of removing the influence of a random subset of the training data from a trained model.

Throughout this process, we explored the following:

• Using gradient checking to make adjustments during gradient ascent
• Implementing gradient ascent forgetting with an interwoven repair step of descent
• Using a good-teacher, bad-teacher, and student framework to remove data influence
• The use of gradient-based weight saliency for data forgetting
