Table 4.

The confusion matrix of the classification results corresponding to Table 3, where “P” represents a certain subtype (e.g., Basal-like) and “N” represents the remaining four subtypes (e.g., Her2, LumA, LumB, and Normal-like). The columns of the confusion matrix represent the reference (i.e., true) class labels, and the rows represent the prediction class labels.
