Fig. 1.

A schematic of the creation of NC models. MCI and AD models are created in a similar manner. Note that M(NC,i) represents the model for channel i trained using the NC training set. Likewise, M(MCI,i) and M(AD,i) represent the models for channel i trained using the MCI, and AD training sets, respectively. Since an EEG record has 32 channels (except 2 ocular channels), there are 30 NC models, 30 MCI models, and 30 AD models.
