Self-generated data

- [Narrator] When I was growing up, … I remember an ad for toys that said … wind it up and watch it go. … But now you can do a similar kind of thing … with data science. … You can do this looping back process. … This is where computers, the algorithms in them, … can engage themselves to create the data they need … for machine learning algorithms. … It's a little bit like the mythical self-consuming snake … that comes all the way back around. … And the reason this is important is because you need data … for training your machine learning algorithms … so they can determine how to categorize something … or the best way to proceed … and having the machines generate it … by engaging with themselves is an amazingly efficient … and useful way of doing that. … There are at least three different versions of this … and I'm giving a little bit of my own terminology here. … The first one is what I am calling … external reinforcement learning. … Now reinforcement learning is a very common term. … It means an algorithm that is designed …
