From: Deep learning and taphonomy: high accuracy in the classification of cut marks made on fleshed and defleshed bones using convolutional neural networks

Figure 4

Heat maps produced by the Grad CAM algorithm indicating discrimination areas important for correct classification of the high-resolution cropped images showing only the mark grooves. (A–C) Cut marks made on defleshed bones. (D-E), cut marks made on bones with meat. Red color in the heat map denotes the most important features.
