Machine Unlearning Idea (IMAGE) Lehigh University Caption The novel approach to making systems forget data is called "machine unlearning" by the two researchers who are pioneering the concept. Instead of making a model directly depend on each training data sample (left), they convert the learning algorithm into a summation form (right) - a process that is much easier and faster than retraining the system from scratch.
