Fig. 9: Confusion matrices of classifiers and pathologists.
From: Deep learning shows the capability of high-level computer-aided diagnosis in malignant lymphoma

The horizontal axis is the diagnosis of the ground truth, and the vertical axis is the predicted diagnosis. The first row/column is DLBCL, the second is FL, and the third is RL. Although the pathologists might confuse the diagnosis between DLBCL and RL, the classifier made only a few errors.
