Abstract :

It is usually assumed that the main frequency components of ERPs are in some specific frequency bands. Therefore, predefined cutoff frequencies are used to filter the raw data in different applications. Here, an extension of the periodic spatial filter method is proposed that jointly learns spatial filters and the corresponding FIR filters to be used for single trial ERP detection. Experimental results confirm that the proposed spatio-spectral filtering method outperforms its predecessor spatial filter.
