Forget Less, Retain More: A Lightweight Regularizer for Rehearsal-Based Continual Learning

Lama Alssum, Hasan Abed Al Kader Hammoud, Motasem Alfarra +2

Deep neural networks suffer from catastrophic forgetting, where performance on previous tasks degrades after training on a new task. This issue arises due to the model's tendency t…
