Implementing a multilayer perceptron (MLP)

A perceptron is composed of a single layer of LTUs, with each neuron connected to all the inputs. These connections are often represented using special pass-through neurons called input neurons: they just output whatever input they are fed. Moreover, an extra bias feature is generally added (x0 = 1).

This bias feature is typically represented using a special type of neuron called a bias neuron, which just outputs 1 all the time. A perceptron with two inputs and three outputs is represented in Figure 7. This perceptron can simultaneously classify instances into three different binary classes, which makes it a multioutput classifier:

Since the decision boundary of each output neuron is linear, perceptrons are incapable of learning complex patterns. However, if the training instances are linearly separable, research has shown that this algorithm will converge to a solution called "perceptron...
