or what's also called a perceptron the idea of a perceptron or a single neuron is very basic and I'll try and keep it as simple as possible and then we'll try and work our way up from there let's start by talking about the forward propagation of information through a neuron we define a set of inputs to that neuron as x1 through XM and each of these inputs have a corresponding weight w1 through WN now what we can do is with each of these inputs and each of these ways we can multiply them correspondingly together and take a sum of all of them then we take this single
