Relation between the EPSP and the Learning Window Henning Sprekeler Christian Michaelis Laurenz Wiskott 10.1371/journal.pcbi.0030112.g003 https://plos.figshare.com/articles/figure/_Relation_between_the_EPSP_and_the_Learning_Window_/619437 <p>The power spectrum is the Fourier transform of the effective learning window <i>W</i><sub>0</sub>, which in turn is the convolution of the learning window <i>W</i> and the EPSP <i>ε</i>. The figure shows the learning windows required for SFA for three different EPSP durations (<i>τ</i> = 4, 40, 400 ms). The maximal input frequency <i>ν</i><sub>max</sub> was 1 / (40 ms) in all plots. </p> 2013-02-21 12:24:27 epsp
