Figure 4.
The prediction results of tumors/normal samples and confusion matrix for 11 cancers. The prediction accuracies of (A) normal tissues and tumors (left), as well as normal tissues and 11 cancer types (right). The x-axis is 100 training/testing times (epochs); and the y-axis presents accuracy of training/testing. (B) The confusion matrix is generated from 4908 independent images. The y-axis is true classes (ground truth) of validation samples and x-axis is prediction classes of CNN model. The diagonal cells are the sample counts of correct prediction/classification. (C) The hierarchical clustering of 1228 samples by using Pearson’s r of gene expression.
