Number of electrodes, seizures, and brain states, and results of the ROC analysis. II, interictal; Post, postictal epoch; Pre, preictal epoch; S/D, number of subdural (S) and depth (D) electrodes; SZ, seizure; “Time” denotes the duration (in hours) of the continuous recordings per patient. The numbers under the column labeled “No. states” indicate the number of brain states uncovered during each period II, Pre, SZ, and Post. The “Earliest max ROC AUC IF/time” is the maximum area under the ROC curve achieved when using the centroid vector obtained in the IF state near the beginning of seizure. The “Earliest max ROC AUC CF/time” is the maximum area under the ROC curve achieved when using the centroid vector obtained in the CF state near the middle-to-end of seizure.
