Fig. 4

A few examples of heatmaps, generated with the attention network’s weights, compared with manual pixel-wise annotations made by pathologist. Each couple of examples includes a heatmap (on the left) and the corresponding pathologist pixel-wise annotations (on the right). The highlighted regions within the heatmaps represent the ones where model assigned the highest importance for the global diagnosis. The comparison of the heatmaps and the annotations shows that the attention network gives greater importance to regions including relevant patches.
