Spectrum (or PCA of spectrum) as part of features #12

Open abuzarmahmood opened 7 months ago

Will have to be done on amplitude normalized waveforms. This will help better target oscillatory noise.

PCA of spectral features (on amplitude normalized waveforms) is strongly informative of spikes vs noise.

Cross-validated accuracy (cv=5) on randomly sampled waveforms using only PCA of spectra of normalized waveforms is high.
