: Unlike standard Fourier or Wavelet transforms, MP adjusts its "analysis window" to fit the actual structure of the signal, allowing it to capture both long-lasting rhythms and very short transients. The Path to Unification
: It typically employs a Gabor dictionary (Gaussian envelopes modulated by sine waves) because these functions achieve the lower bound of the uncertainty principle, providing the most concentrated time-frequency representation. Matching Pursuit and Unification in EEG Analysi...
: In each step, the algorithm selects the waveform that best fits the local signal structure, subtracts it, and repeats the process on the remaining residue. : Unlike standard Fourier or Wavelet transforms, MP
