The proposed work employed five feature extraction measures: Higuchi’s FD, Katz FD, Petrosian FD, spectral entropy, and permutation entropy. All the mentioned feature extraction methods were implemented using Antropy, Pandas, and NumPy Python libraries. A brief overview of each method is given in...
