FIGURE 2.

The implemented statistical method for considering the imbalanced trials. In section (A), the calculation of feature values has been shown. In the upper section, features from the actual conditions (V1, V2) have been calculated and then subtracted for each subject. In the lower section of (A) the same procedure is happening but with random shuffling of the labels across trials for 1,000 iterations. In section (B) we averaged the outcome of section (A) over subjects which the upper section shows for the actual condition and the lower section is for each iteration. In section (C) the ground truth value from the actual conditions and null distribution from the random shuffling is illustrated in the upper and lower side respectively.
