One, two, three. One, two, three. One, two, three. >> Hey guy's what do you doing? >> Hello got a friend over here. Who are you? >> I'm Kevin. >> That's nice I'm Yoav >> I'm Matt. I guess we're going to play a new game? >> What do I do suggest? >> How about some black jack? >> I could do that. >> Yeah sure. >> That's an obvious. So let's play for low stakes, okay, say a thousand dollars? >> [LAUGH] It's a deal. >> All right. >> Let's see who wins. >> All right, deal me in. >> want to card? >> Okay, hit me. >> What are the rules again? >> Well, you try and get to 21. Anybody gets to 21 wins. If you go over 21, you're going to lose. >> I see. I don't know, I guess I'll save. >> Do you want to. >> No, I guess I'll save what I have. >> I will take one more. I'm over. >> Alright, I'll stay. >> So what happens now? >> Well, you guys figure out who's got the most. >> Alright, I've got 19 here >> Would you know, look what I got! 21. >> Blackjack. >> Wait, I think there's some other people watching us here, we ought to introduce ourselves a little bit more formally. >> Alright, I'll start. I'm Kevin. I'm an Associate Professor of Computer Science at the University of British Columbia in Vancouver, Canada. My research is on artificial intelligence, game theory, electronic commerce, and algorithms. >> I'm Matt Jackson, I am a professor of economics at Stanford University and I do research on game theory, and social networks, and a variety of micro-economic topics. >> And I am Yoav Shoham, I am also a professor here at Stanford. Like Kevin I am also a computer scientist in artificial intelligence and electronic commerce and game theory. And we're here to co-teach the class on game theory. So maybe let's start by saying a little bit about what game theory is about and as importantly what it's not about. So often we think about game. We do think about things, such as rock, paper, scissors, or poker, or sports games like soccer and baseball but really game theory is about all kind of strategic interactions among self interested agents Including those frivolous ones, but also much more serious ones. Matt, you're an economist, tell us more about serious games. >> Sure, game theory has become a really essential tool to understanding a lot of different interactions, anything from auctions, to people's behavior in financial markets. To even international conflict to understanding political interactions. So it's become an essential part of any social scientists' toolbox and indeed it's actually used even beyond that so things like biology, predator prey games, a whole series of things. >> It's really a fairly widely applicable thing in any situation where there's competition, strategic interaction. So it's a lot to cover here. >> That makes sense. But now, Kevin, you and I are computer scientists, what are we doing here? >> Well, these days game theory has become a really hot area in computer science. Basically for two reasons. First of all, computers are increasingly away of bringing people together and that means we have to think about how people interact when we bring them together. And that's true whether you think about networks, keywords options that forms the basis of almost all of google revenues, peer-to-peer file sharing systems,or consumer sites like eBay or TripAdvisor or Yelp. To understand how any of these systems work,we really have to think about how their participants are self-interested, and how those interests drive their behavior. The second thing is that the sorts of economic settings that a game theoretic economist like math study, as they scale up and get bigger, they start to encounter computational dimensions. And to make the right kind of sense of those and bring these things into practice in the real world, it's really necessary to think about them in terms of algorithms, complexity theory and artificial intelligence. >> So let's speak a little bit about our class. Firstly, set expectations for all these potential applications we're discussing. Our class will really be very fundamental but very fundamental modeling tools here. We'll not attempt to advise people on how to use it really in the real world any direct way. We'll only use examples by way of illustrating the formal constructs. So, let's speak a little bit about the syllabus. >> Sure. So, the course will run about seven weeks. It's really an introductory course. It doesn't presume that people have any experience in game theory before, assume a tiny bit of background and probability and calculus. But generally, it should be accessible to a pretty wide range of people. Our intention is just to show people how our game is structured, how do we think about strategic interaction between people will start with equilibrium notions. We'll talk about incomplete information. We'll talk about timing repeated games. We'll also talk about coalitional structures. So we have quite a bit of things to cover. But it should be a very fun course for. >> Kevin, you want to speak a little bit about some of the mechanics and what people need to do and so on? >> Sure, so, there's a lot to this course besides just the videos. Some of these things are going to be graded, and others not. So on the graded side, there are three key components >> The first of quizzes that happen after the videos that you can use to test your comprehension and if you find that you get some of the questions wrong that might indicate to you that you should go back see the video again and make sure that you know everything you need before you proceed to the next material. >> The second element is discussion boards which you can use to ask questions about the parts of the course that you're finding confusing. And also to raise logistical questions about the course. And those discussion boards will be answered by other participants in the course, by teaching assistants and also by Matt, Yoav and me. The third element is lab exercises where you can optionally play some of the games that we actually introducing in the course. See how would you reason in this game yourself and then will have a chat rooms as part of the labs where in real time you can actually talk to other people from the course, share your experiences about what you learned and see what they have to say. On the graded side, we'll have a weekly problem sets which will be sort of like the quizzes but in a bit more detail. They'll give you a chance to show what you've learned from the material in that week and we'll have a final exam that will cover the whole course. Each of these you can take only once and as I said they'll be graded. We use that grade as the basis for your certificate of completion. So if you get all the way through the course, you'll get a certificate that's signed by all three of us. >> And that would be a total of seven weeks, as we've said. We should also mention that this is a very large class. There's many tens of thousands of students here. So, we'll do our best to be clear in our presentations, but a lot of it will involve help among the students themselves. So, there are online forums and they're an essential part of the class. You really want to form study groups to consult each other on the problem sets, on the lectures. We do have a TA's that will monitor the forums, both TA's at British Columbia and at Stanford, as well as community TA's that have stepped up. But at the end of the day, it'll only work if, as a community we all Work together. Please because of large numbers don't send us personal email. It's not that we don't like to speak to you. We just won't be able to handle it. So we won't be able to respond. Similarly there is the class website, on the class website as well as on the social media. If you want to kind of follow us personally on our personal sites, by all means, but no please, friend requests and so on again. The numbers are so large, we won't be able to respond. This is really going to be a fun class isn't it? >> Yeah. I'm looking forward to it. Should be a great time. >> You know I had a lot of fun with that previous game. >> Yeah. And actually, I think it's time for Kevin and I to win some money back. >> Well, let's see how good you are. >> [LAUGH] Okay.
