DSS: A Diverse Sample Selection Method to Preserve Knowledge in
  Class-Incremental Learning
Sahil Nokhwal Nirman Kumar
Rehearsal-based techniques are commonly used to mitigate catastrophic
forgetting (CF) in Incremental learning (IL). The quality of the exemplars
selected is important for this purpose and most methods do not ensure the
appropriate diversity of the selected exemplars. We propose a new technique
"DSS" -- Diverse Selection of Samples from the input data stream in the
Class-incremental learning (CIL) setup under both disjoint and fuzzy task
boundary scenarios. Our method outperforms state-of-the-art methods and is much
simpler to understand and implement.
