This study introduces an adaptive feature selection method using V-shaped binary particle swarm optimization. It effectively evaluates feature subsets for improved machine learning model performance and interpretability.

Area of Science:

  • Machine Learning
  • Data Mining
  • Computational Intelligence

Background:

  • Feature selection is crucial for reducing data dimensionality and enhancing model interpretability in machine learning.
  • Traditional methods often assess feature dependency and redundancy in isolation, neglecting their combined impact.
  • Greedy search strategies in conventional methods limit the scope of optimization to local optima.

Purpose of the Study:

  • To propose an adaptive feature selection method that evaluates the combined effect of feature subsets within the entire feature space.
  • To enhance the global search capability and overcome limitations of traditional feature selection techniques.
  • To improve the efficiency and effectiveness of feature subset selection in machine learning tasks.
