A Novel Fixed Low-Rank Constrained EEG Spatial Filter Estimation with Application to Movie-Induced Emotion Recognition

Figure 13

(Positive versus neutral) scalp maps of spatial filters obtained by the proposed method with rank 6 constraint for all subjects. The row specifies subjects “S1”–“S10” from top to bottom. The column specifies six spatial filters defined by left singular vectors of corresponding to the highest six eigenvalues from left to right. The number above each topography is the percentile of corresponding singular value. The superscript () indicates that the pair of left and right singular vectors differs in sign.
