Comparison results on the robustness of methods: AUC values on simulation data sets with different signal-to-noise levels for network-constrained SVM and conventional SVM. AUC values are calculated based on 100 simulations, where standard deviations are shown in the error bars. (a) perturbing all ground truth genes in testing data sets; (b) perturbing hub genes (of node degree > 10) in testing data sets.
