internals but we'll talk about how we can actually tackle some of those challenges in later lectures as well okay so now that we have that idea of a perceptron a single neuron let's start by building up neural networks now how we can use that perceptron to create full neural networks and seeing how all of this story comes together let's revisit this previous diagram of the perceptron if there are only a few things you remember from this class try to take away this so how a perceptron works just keep remembering this I'm
