Table 2.

Comparison of different methods using TCGA breast cancer (K = 5). G3 represents feature groups (gene symbol) where all three types of features are selected. Similarly, G2 represents feature groups (gene symbol) where only two types of features are selected; G1 represents feature groups (gene symbol) where only one type of feature is selected. We also compared the clustering result with PA M 50 subtype definition in terms of ARI
