Figure 5

SmoothGrad heatmaps of exemplary patches that were classified correctly. For each class, the upper plot shows the original image patch while the lower plot shows the patch overlaid with the SmoothGrad heatmap with respect to the class of the patch. High SmoothGrad activity scores can be seen in areas overlaid with single cells, as well as in lung LN with extracellular anthracosis. This confirms that the algorithm classified the image patches on the basis of cellular and extracellular morphological structures. DLBCL: diffuse large B-cell-lymphoma, LN: lymph node, SLL/CLL: small lymphocytic lympho-ma/chronic lymphatic leukemia. Magnification: each image 100 × 100 µm (395 × 395 px).
