The Pitfalls of Memorization: When Memorization Hurts Generalization

Reza Bayat (Mila), Pascal Vincent (Mila)

ClassificationDomain AdaptationImageText

🎯 What it does: This paper studies the interaction between 'memorization' and 'false association' that occurs during the learning process of neural networks, proving that the combination of the two can lead to model generalization failure under distribution shift. It proposes a novel training method called Memorization-Aware Training (MAT), which uses the predicted probabilities of retained samples to adaptively shift logits, thereby guiding the model to learn robust features across distributions.
