This is especially true when IL is modeled using a deep learning approach, where two complex challenges arise due to limited memory, which induces catastrophic forgetting and delays related to the retraining needed in order to incorporate new classes. It is (I suppose) more straightforward. Question: how to extract the exemplars? 5 Paper Code Rebuffi, A. Kolesnikov, and C.H.

This violates the assumptions that underlie methods for training standard deep neural networks, and will cause them to suffer from catastrophic forgetting. For representation learning, the training set is constructed by mixing all the samples in the memory buffer and the current task samples. "icarl: Incremental classifier and representation learning."
