bookIntroduction To Active Learning

Active Learning is a machine learning approach that aims to maximize model performance while minimizing labeling effort. Rather than labeling data samples at random, you use algorithms to systematically select the most informative examples from a pool of unlabeled data. These are the data points that, if labeled and added to the training set, are expected to provide the greatest improvement to your model.

This process usually involves:

  • Evaluating which unlabeled data points the model is most uncertain about;
  • Selecting those uncertain or informative examples for labeling by a human or an expert;
  • Updating the model using the newly labeled data to improve its accuracy and generalization.

By focusing labeling resources on the most valuable examples, Active Learning helps you achieve high accuracy with fewer labeled samples, making it especially useful when labeling is expensive or time-consuming.

Note
Definition

Label efficiency measures how well a machine learning system achieves high accuracy with fewer labeled examples. This is vital for reducing costs and making machine learning possible in fields where labeling is expensive or requires expert knowledge.
