Boxplot depicting the decoding accuracies obtained using two different training scenarios. In the first scenario (Ind set train), individual dataset accuracies were obtained by using training samples only from that particular dataset. For example, to calculate the test accuracy of FAU_Dataset, training samples were taken only from FAU_Dataset. In the second scenario (Full set train), individual dataset accuracies were obtained using training samples from all the three datasets combined. As a result, there are more training samples in the second scenario compared to the first (^*p < 0.05; ^**p < 0.01; ^***p < 0.001 based on paired Wilcoxon signed-rank test).
