Dimensionality Reduction and Channel Selection of Motor Imagery Electroencephalographic Data

<table>Timing of a trial of the training paradigm. The time slice between seconds 4.5 and 5.5 was used to train the classifiers. In the case of CSP the same time slice was also employed to calculate the spatial filters. However, for calculating ICA spatial filters the entire time period (0–7.5 seconds) was used.</table>
