Spatial Classification. Spatial distribution of the AUC scores for ErrP classifiers of type-A (top) and type-B (bottom) shown as scalp topography. Classification was performed for each channel separately. Peak performance was reached at central regions for both types (A:0.67, B: 0.8), frontal regions are near chance level. The performance is higher for type-B than for type-A classifiers in all regions.
