Legend: Training accuracy is the ratio of correct predictions over total predictions made by the model. Training precision is the ratio of true positives over all positive classifications (true and false positives). Training recall is the ratio of true positives over all actual positives (true positive and false negatives). Training scores computed by game performance was calculated by total trials correct/total trials. MI: motor imagery
