This study presents an efficient radial basis function (RBF) neural classifier for high-dimensional face recognition with small datasets. The method enhances classification accuracy and learning efficiency by combining principal component analysis (PCA) and Fisher

Area of Science:

  • Computer Science
  • Artificial Intelligence

  • To address the challenges of small training sets and high dimensionality in face recognition.
  • To improve classification accuracy and learning efficiency in facial recognition systems.

Main Methods:

  • Feature extraction using Principal Component Analysis (PCA) to reduce dimensionality and mitigate overfitting.
