 Machine learning is about optimization. In learning via optimization, we define an error function (loss function) on the model and try to optimize it, i.e., try to find the optimal parameters of the model by optimization techniques borrowed from optimization literature.

 There are three types of neurons (units) in ANN. Each unit except the input unit takes an input and calculates an output. Input units represent a single input feature x<sub>i</sub> or the bias = +1. Hidden units calculate an intermediate output from its inputs. They first combine their inputs linearly and then use nonlinear activation functions to map that linear combination to a nonlinear space. Output units calculate the output of the ANN.
