In supervised learning, acquiring labeled training data for a predictive model can be very costly, but acquiring a large amount of unlabeled data is often quite easy. Active learning is a method of obtaining predictive models with high precision at a limited cost through the adaptive selection of samples for labeling. This paper explains the basic problem settings of active learning and recent research trends. In particular, research on learning acquisition functions to select samples from the data for labeling, theoretical work on active learning algorithms, and stopping criteria for sequential data acquisition are highlighted. Application examples for material development and measurement are introduced.

    cs.LG 2025-06 conditional novelty 6.0 of 10

    A data-model coevolution framework that fuses model and nearest-neighbor predictions to select labels, reaching ImageNet-1K accuracy with 68% of annotations and 50% under semi-supervised training.

  2. Cost-effective Reduced-Order Modeling via Bayesian Active Learning

    cs.LG 2025-06 conditional novelty 4.0 of 10

    An active learning framework for reduced-order models, BayPOD-AL, shows that an error-bounded acquisition function outperforms uncertainty sampling and random sampling on a 1D heat equation surrogate task.
