Discriminative power of different types of markers. We evaluated the discriminative power of the subnetwork markers identified using the proposed method, and compared them with gene markers, pathway markers , and the subnetwork markers identified by Chuang et al. . Mean absolute t-score is shown for the top K = 10, 20, 30, 40, 50 markers. (A), (B): Markers were identified using a particular dataset and tested on the same dataset. (C), (D): Markers were identified using the first dataset and evaluated based on the second dataset.
