Apple Research: Low-Impact Points Reduce Unlearning Costs

Apple ML Research · rss · 2026-07-17

This Apple ML Research paper addresses the challenge of "unlearning." When removing specific data points from a trained model, existing methods typically treat all samples in the forget set equally, which isn't always necessary.

The authors suggest using influence functions to analyze how training samples affect model outputs. By identifying low-impact data points, they can narrow down the scope of samples requiring processing, thereby reducing the computational costs of unlearning. The paper includes a comparative analysis across both language and vision tasks.
