Researchers have introduced TypiCore, a novel hybrid active query strategy designed for class-incremental learning on time series data. This method addresses the challenge of learning new classes sequentially from unlabeled data streams by selectively querying labels under a fixed budget. TypiCore alternates between typicality-based and diversity-based sample selection to build memory buffers that are both representative and diverse. Evaluations on benchmark datasets show that TypiCore significantly outperforms existing methods and matches fully supervised continual learning performance while using substantially fewer labels. AI
