A three layer <a href="https://en.wikipedia.org/wiki/Perceptron" class="extiw" title="en:Perceptron">Perceptron</a> net capable of calculating <a href="https://en.wikipedia.org/wiki/XOR" class="extiw" title="en:XOR">XOR</a>. The numbers within A-elements represent each perceptrons' explicit threshold. The numbers that annotate arrows represent the weight of the inputs. This net assumes that if the treshhold is not reached, zero (not -1) is output. Note that the left layer of inputs is not always considered a real perceptron layer.
