(a) The importance ranking of each node’s homogeneity for multiclass task classification. The darker color represents higher importance. (b) The lobe distribution of the twenty most important nodes for task classification. (c) The distributions of homogeneities for the three most important nodes and three least important nodes for multiclass task classification under different tasks. The gray distributions show the homogeneities under REST for 493 subjects and the distributions in other colors represent the homogeneities under other tasks labeled on the x axis. Paired t-test was used to compare the homogeneity distributions under REST and tasks. The p values are reported (above each pair of distribution). (d) The multiclass task classification accuracies for each task and the total accuracy using homogeneity vectors containing the fifty most node homogeneities. (e) The multiclass task classification accuracies for each task and the total accuracy using homogeneity vectors containing the fifty least node homogeneities.
