Diagram of a simple feedforward neural network showing three layers: green input nodes at the bottom, yellow hidden layer nodes in the middle, and blue output nodes at the top, with arrows indicating one-way signal flow from input to output.

A section of an artificial neural network. The weight, or strength, of each input is indicated here by the relative size of its connection. The firing threshold for the output neuron, N, is 4 in this example. Hence, N is quiescent unless a combination of input signals is received from W, X, Y, and Z that exceeds a weight of 4.
