Perceptron¶. Each node in a neural network is called a perceptron unit, which has three “knobs”, a set of weights (\(w\)), a bias (\(b\)), and an activation function (\(f\)).The weights and bias are learned from the data, and the activation function is hand picked depending on the network designer’s intuition of the network and its target outputs.
