Introduction to deep learning

“

- Let's do a simple introduction to deep learning, where we're going to look at an analogy that involves a factory and a shipping warehouse. Now, a deep learning diagram that shows a neural network is going to start with the input layer. Well, what exactly is the input layer? Let's take a look here. When we have a factory where we are producing goods and we have to actually make them or assemble them in the factory, this would be like the loading dock where we get all of the raw materials. And so each item that comes into the loading dock is a different feature of the data, like an image pixel, or a measurement, or some metadata key value pair. The input layer is going to take all of these and then prepare them for the next layer, which is processing. And this is what we call the hidden layers within a neural network, now, there's a lot of magic that's happening here, and so let's take a look at our diagram. And so these would be like the various assembly workers in the factory. Each…
