Definition

Active learning reduces the amount of labeled data required by allowing the model to choose the most informative instances for human labeling. Instead of passively receiving random samples, the algorithm identifies regions of high uncertainty or potential impact and requests labels specifically for those cases. This iterative process significantly lowers annotation costs and accelerates convergence, making it ideal for scenarios where data labeling is expensive, time-consuming, or requires specialized expertise.
