Description ActiveLearn Loop is an active learning module for teams that need to reduce labeling cost while improving model quality through intelligent sample selection. In many AI projects, the limiting factor is not model architecture but the lack of high value labeled examples. Randomly labeling more data often wastes time because many samples are repetitive, easy, or irrelevant. This module helps identify uncertain, diverse, high impact, or strategically valuable samples so that human reviewers can focus on the data most likely to improve the model. It can be used in classification, ranking, forecasting review, document labeling, image labeling, anomaly review, and human feedback workflows. A typical workflow is to run a model on unlabeled or weakly labeled data, score samples by uncertainty or disagreement, select batches for human review, collect labels, retrain or fine tune the model, and repeat the loop. The module is especially useful when paired with AnnotationFlow Studio, HumanReview Queue, FeedbackLoop Collector, and LabelWorks. It does not replace human judgment or guarantee automatic model improvement. Users must design sampling policies carefully, review class balance, avoid bias amplification, and validate whether each labeling round actually improves business relevant metrics.
