-What we are essentially describing is a Multilayered perceptron (MLP) with an architecture as illustrated in \figref{fig:xor_mlp_arch}. This MLP is made up of an output layer with a single output neuron ${\color{blue}s^2_1}$, and one hidden layer with two hidden neurons, ${\color{magenta}s^1_1}$ and ${\color{green}s^2_2}$ (the superscript denotes the layer index, the subscript denotes the neuron index within its layer). The terms ``neurons'' and ``nodes'' are treated as synonyms.
