Unique participant counts are reported separately for each partition. These counts are not additive in the fixed 80:20 analysis because different electroencephalography segments from the same participant could occur in both the training and test partitions. Therefore, the fixed analysis represents a window-level internal evaluation. Participant-grouped five-fold cross-validation with complete participant separation was used separately to estimate generalization to unseen participants within the same source dataset.
