Notes. For the capsule networks, an image was classified as containing a light echo if the length of the final capsule was greater than 0.5. For the CNNs, an image was classified as containing a light echo if the neuron corresponding to the light echo class was more active than the non-light-echo class neuron. The model loss is given by the margin loss for capsule networks, and cross-entropy loss for CNNs.
