Fig. 3From: A dimension reduction technique applied to regression on high dimension, low sample size neurophysiological data setsEvent-related potentials for a representative participant (the same as in Fig. 2). Averaged ERPs for stimuli #1, #2, #3, #4, and #5 are shown from top to bottom. Only the 128 wavelet components in the low frequency bands (below 156 Hz) are considered for the signal reconstruction. Due to the baseline correction, all signals are close to zero at \(t =\) 0 s. The signals are displaced vertically for the sake of visualizationBack to article page
