Deep learning neural networks

- [Instructor] If you've ever been around a baby, … you know that babies take very little steps. … But the thing about baby steps is that you still get moving … and eventually, babies grow and they take bigger steps. … And before you know it, you've got a world-class sprinter. … And there's a similar thing, I like to think, … that happens with neural networks. … And what happens here is that tiny steps with data … can lead to amazing analytical results. … Now, an artificial neural network in computing … is modeled roughly after the neurons … that are inside a biological brain. … Those neurons are nothing more … than simple on and off switches … that are connecting with each other, … but give rise to things like love and consciousness. … In the computing version, the idea is to take some … very basic pieces of information, … and by connecting it with many other nodes, … you can give rise to the sort of emergent behavior, … which really is very high-level cognitive decisions … and classifications. …
