Temporal signal ratio features. An example showing how the temporal signal ratio features are computed for an EEG channel. The ratio of statistics (such as mean) of the signal in the last half (Window2 here) to that in the first half (Window1 here) is taken as a feature. The temporal signal ratio features are computed for each EEG channel. Additional features summarizing the ratio features across the channels are also computed
