Integration of three additional features versus: (A) Four original features. Integration of three additional features (EXP, MES, APA) shows an improvement over the original four features at all range of FPRs. (B) Two original features. By excluding the two strongest features (MIP, GOF), it becomes more obvious that integrating three additional features outperforms the original two features. The insets are a closer look at the small FPR region by taking a log-scale of the x-axis. TPR, FPR, TP, FP, P, N are the same as in Figure 3.
