This study introduces pruning and model-selection algorithms for support vector learning, optimizing Radial Basis Function (RBF) networks by removing redundant support vectors to improve classification and regression accuracy.

Area of Science:

  • Machine Learning
  • Artificial Intelligence
  • Computational Science

Background:

  • Support Vector Learning (SVL) is used for classification and regression.
  • Radial Basis Function (RBF) networks constructed via SVL can contain redundant support vectors.
  • These redundant vectors do not significantly impact final results but increase model complexity.

Purpose of the Study:

  • To develop and present pruning and model-selection algorithms for support vector learning.
  • To optimize the structure of Support Vector Machine (SVM) networks.
  • To enhance the flexibility and efficiency of SVM models in classification and regression tasks.

Main Methods:

  • Algorithms based on sensitivity measure and penalty terms are employed for pruning.
