From: Spike sorting by a minimax reduced feature set based on finite differences
A comparison of the performances of mRFS, WSC, RFS, and PCA methods on real neuronal spikes. The superimposed spikes consisted of 8,910 spikes; the width of each waveform is 1.6Â ms, which covers the entire spike. The plot of mRFS was chosen from 16 plots, while the plots of the other three methods were chosen from 496 plots. Notice that the mRFS plots display more-distinct clusters in this case
