Heatmaps emphasize the key regions of the input image that significantly affect the outcomes. The colors represent the relevance of each pixel to the model’s decision. a The average heatmap, created by overlaying 10,000 maps for each class, demonstrates which signal parts influence the decisions for each class across numerous samples. b Representative samples that vividly highlight distinctive features characteristic of each class.
