a Embeddings of the training set. b Embeddings of the validation set. Each point in the maps represents an image embedding of the colour coded emperor. These are points taken from the penultimate dense layer of the model from experiment 2, which is a 512-dimension representation. Observe that the same emperor embeddings are grouped well together and are well separated from one another.
