Error Sensitivity Modulation based Experience Replay: Mitigating Abrupt Representation Drift in Continual Learning

ICLR 2023poster

Humans excel at lifelong learning, as the brain has evolved to be robust to distribution shifts and noise in our ever-changing environment. Deep neural networks (DNNs), however, exhibit catastrophic forgetting and the learned representations drift drastically as they encounter a new task. This allud…

Sparse Coding in a Dual Memory System for Lifelong Learning

AAAI 2023technical

Efficient continual learning in humans is enabled by a rich set of neurophysiological mechanisms and interactions between multiple memory systems. The brain efficiently encodes information in non-overlapping sparse codes, which facilitates the learning of new associations faster with controlled inte…

Learning Fast, Learning Slow: A General Continual Learning Method based on Complementary Learning System

ICLR 2022poster

Humans excel at continually learning from an ever-changing environment whereas it remains a challenge for deep neural networks which exhibit catastrophic forgetting. The complementary learning system (CLS) theory suggests that the interplay between rapid instance-based learning and slow structured l…
