A Comparative Study of Calibration Methods for Imbalanced Class Incremental Learning

no code implementations1 Feb 2022 Umang Aggarwal, Adrian Popescu, Eden Belouadah, Céline Hudelot

Since memory is bounded, old classes are learned with fewer images than new classes and an imbalance due to incremental learning is added to the initial dataset imbalance.

Optimizing Active Learning for Low Annotation Budgets

no code implementations18 Jan 2022 Umang Aggarwal, Adrian Popescu, Céline Hudelot

It consists in learning a model on a small amount of annotated data (annotation budget) and in choosing the best set of points to annotate in order to improve the previous model and gain in generalization.

Active Class Incremental Learning for Imbalanced Datasets

1 code implementation25 Aug 2020 Eden Belouadah, Adrian Popescu, Umang Aggarwal, Léo Saci

Most existing algorithms make two strong hypotheses which reduce the realism of the incremental scenario: (1) new data are assumed to be readily annotated when streamed and (2) tests are run with balanced datasets while most real-life datasets are actually imbalanced.
