Continual Prototype Evolution: Learning Online from Non-Stationary Data Streams [article]

Matthias De Lange, Tinne Tuytelaars
2021 arXiv   pre-print
However, learning prototypes online from streaming data proves a challenging endeavor as they rapidly become outdated, caused by an ever-changing parameter space during the learning process.  ...  Additionally, continual learning does not assume the data stream to be stationary, typically resulting in catastrophic forgetting of previous knowledge.  ...  In this challenging setup, we proposed Continual Prototype Evolution (CoPE) as a prototypical solution to learn online from non-stationary data streams.  ...
