AI generated summary

Online learning of image classifiers with expanding labels

This paper proposes a new continual learning setup called hierarchical label expansion that simulates real-world knowledge accumulation, where learning begins with coarse categories that expand into finer subcategories over time. The paper introduces a method to tackle this setup using pseudo-labeling, flexible memory sampling, and hierarchy-aware training.
