Animated Neural Network — A small network with a feedback loop. This is a cartoon of a very simple fully-connected (FC) neural network with input (X), three FC hidden layers (H1, H2, H3) and the output (Y). The input was intentionally made to send information through hidden-layer neurons at different times, to make it easier for the viewer to follow the motion of the moving arrows (movement of data through the network). In practice, the information from one layer to the next practically travels at the same time
