Abstract: Recently N-way Partial Least Squares (NPLS) were reported as an effective tool for neuronal signal decoding and BCI system calibration. This method simultaneously analyses data in several domains. It is based on the projection of a data tensor to a low dimensional space using all variables to create a final model. In the present paper the L1-Penalized NPLS is proposed for sparse BCI system calibration allowing to combine the projection technique with an effective selection of subset of features. The L1-Penalized NPLS was applied for binary self-paced BCI system calibration providing a subset of electrodes selection. Our BCI system is designed for animal research in particular for research in non-human primates.
