ROC curves of the four gene selection methods on the dataset of Platinum Spike. The red, orange, blue and purple lines depict the ROC curves of Two-way rectification using Min-Edge, Min-Edge, Two-way rectification using ModT and ModT, respectively. The AUC value of Two-way rectification using Min-Edge is 0.943028, which is higher than that of the other three algorithms
