This study introduces an ensemble learning method with active example selection to address imbalanced biomedical data. The novel approach improves prediction performance for minority classes, outperforming existing under-sampling techniques.

Area of Science:

  • Biomedical data analysis
  • Machine learning in healthcare

Background:

  • Imbalanced data is a common challenge in biomedical research, leading to poor prediction accuracy for underrepresented classes.
  • Existing methods often fail to adequately address the bias towards majority classes in classifier training.

Purpose of the Study:

  • To develop and evaluate a novel ensemble learning method combined with active example selection for imbalanced biomedical data.
  • To enhance prediction performance for minority classes in imbalanced datasets.

Main Methods:

  • An active example selection algorithm identifies informative training data points.
  • An ensemble learning approach combines multiple classifiers trained via active example selection.
  • An incremental learning scheme accelerates the iterative training process.
