I'm posting this here mostly for the image, and you don't even see the image in the Reddit version unless you click on a specific link. the image makes clear in a way no number of would could the relation between a network (that is, the graph, that is, the nodes connected by connections) and a matrix (that is, a set of numbers arranged in rows and columns, which also denote the connections). Most neural net software is based on performing mathematical operations on the *matrix*, but that's hard to visualize when looking at patterns in the network. The rest of the post is pretty interesting, but the whole point is really made with the diagram.
