Input shapes for each network type are illustrated: (a) The CNN input shape was expanded about the channel (electrode) dimension as the number of filters increased; (b) The LSTM input flattened the electrode and frequency dimensions into a single combined dimension; (c) All dimensions were flattened into a single input vector for the ANN.
