Visualization of (a) HMP, (b) IBD, and (c) PDX datasets using t-SNE projection [33]. We project the activation function of the last hidden layer of the test data onto a 2D space, where different colors represent different classes. For instance, the red and green colors represent samples collected from anterior nares and stools, respectively. As it can be seen, HMP and IBD samples show a clear separation between classes, while PDX samples are hard to be distinguished
