This study introduces efficient methods for selecting centroids in Radial Basis Function (RBF) classifiers, improving performance and reducing units compared to support vector machines (SVMs). These novel RBF classifiers offer a promising alternative for machine learning tasks.

Area of Science:

  • Machine Learning
  • Artificial Intelligence
  • Pattern Recognition

Background:

  • Support Vector Machines (SVMs) are effective but can be computationally intensive.
  • Radial Basis Function (RBF) classifiers offer an alternative with potential for reduced complexity.
  • Efficient centroid selection is crucial for optimizing RBF classifier performance.

Purpose of the Study:

  • To explore direct sample selection methods for constructing RBF classifiers.
  • To investigate RBF classifiers that utilize a reduced number of samples as centroids, similar to SVMs.
  • To compare the performance of these novel RBF classifiers against existing methods like SVMs.

Main Methods:

  • Sample selection for centroids performed after vector quantization.
