Choosing the right electroencephalogram (EEG) features is crucial. Fractional Fourier transform coefficients show strong performance for EEG classification tasks, with potential for improved accuracy through feature combinations.

Area of Science:

  • Neuroscience
  • Signal Processing
  • Machine Learning

Background:

  • Electroencephalogram (EEG) feature extraction involves numerous methods, necessitating careful selection for specific applications.
  • The optimal choice of EEG features significantly impacts the performance of machine learning models in classification tasks.

Purpose of the Study:

  • To compare the efficacy of three distinct EEG feature extraction techniques: tracks extraction, wavelet transform, and fractional Fourier transform.
  • To evaluate the performance of these feature subsets in EEG classification using Support Vector Machines (SVM).
  • To identify optimal feature combinations for enhanced classification accuracy.

Main Methods:

  • EEG features were extracted using tracks extraction, wavelet transform, and fractional Fourier transform.
