How active learning can train machine learning models with less data

  • Random sampling: the data points are sampled at random.
  • Uncertainty sampling: Points are selected based on the ML model’s prediction uncertainty of their class.
  • Entropy sampling: Points are selected with maximal class probability entropy.
  • Margin sampling: Points are chosen for whom the difference between the most and second most likely classes are the smallest.
  • The probabilities in these strategies are associated with the predictions of the SVM classifier.
