Activation Maps for the 1st (input), 5th, 16th, and 22nd layers. Note that magnitude of values in the intermediary layers before the final sigmoid layer depend on the choice of the activation function and do not have physical meaning. The numbers of channels represented are indicated on top of each plot. Note the decreasing image size as evident by the number of pixels shown on the axes. The ___location of the image is show on the upper left corner for text. The scalebar for the input is given on the upper right corner. The dilation rates for Layer 22 are 1, 2, 3, 4 for channels 22, 164, 322, and 482, respectively. The activation maps and the labels on the inset of Antarctica are plotted using Matplotlib version 3.3.219. The Antarctic map is created using the default low resolution Earth map in Geopandas version 0.6.131 and plotted in Antarctic polar stereographic (EPSG:3031) projection. All libraries are used with Python 3.7.417.
