- I'm Neil and I'm Tim and today we are talking about AI or artificial intelligence.0:12
- Artificial intelligence is the ability of machines to copy human intelligent behaviour.0:19
- For example, an intelligent machine can learn from its own mistakes and make decisions based on what's happened in the past.0:25
- There's a lot of talk about AI these days Neil, but it's still just science fiction, isn't it?0:32
- That's not true.0:37
- AI is everywhere.0:39
- Machine thinking is in our homes, offices, schools and hospitals.0:40
- Computer algorithms are helping us drive our cars.0:45
- They're diagnosing what's wrong with us in hospitals.0:48
- They're marking student essays.0:51

- Well, that really does sound like science fiction, but it's happening already you say Neil.0:56
- It's definitely happening Tim.1:01
- And an algorithm by the way is a set of steps a computer follows in order to solve a problem.1:03
- So, can you tell me, what was the name of the computer which famously beat world chess champion Gary Kasparov using algorithms in 1997?1:08
- Was it a Hal, B, Alpha 60 or C, Deep Blue?1:18
- I'll say Deep Blue, although I'm just guessing.1:24
- Was it an educated guess Tim?1:28
- I know a bit about chess.1:30
- An educated guess is based on knowledge and experience and is therefore likely to be correct.1:31
- Well, we'll find out later on how educated your guess was in this case Tim.1:37
- Indeed.1:41
- But getting back to AI and what machines can do.1:42
- Are they any good at solving real life problems?1:45
- Computers think in zeros and ones don't they?1:50
- That sounds like a pretty limited language when it comes to life experience.1:52
- You would be surprised at what those zeros and ones can do Tim.1:56
- Although you're right that AI does have its limitations at the moment.2:00
- And if something has its limitations there's a limit on what it can do or how good it can be.2:04
- OK, well now it might be a good time to listen to Zubin Bachramani, Professor of Information Engineering at the University of Cambridge and Deputy Director of the Leyva -Hulmer2:08
- Center for the Future of Intelligence.2:20
- He's talking about what limitations AI has at the moment.2:23
- I think it's very interesting how many of the things that we take for granted, that we humans take for granted as being sort of things we don't even think2:28
- about.2:37
- Like how do we walk, how do we reach, how do we recognize our mother, you know, all these things.2:37
- When you start to think about how to implement them on a computer, you realize that it's those things that are incredibly difficult to get computers to do.2:44
- And that's where the current cutting edge of research is.2:55
- If we take something for granted we don't realize how important something is.3:01
- You sometimes take me for granted, I think Neil.3:05
- No, I never take you for granted Tim, you're far too important for that.3:09
- Good to hear.3:13
- So things we take for granted are doing everyday tasks like walking, picking something up, or recognizing somebody.3:14
- We implement or perform these things without thinking, whereas it's cutting edge research to try and program a machine to do them.3:23
- Cutting edge means very new and advanced.3:32
- It's interesting isn't it that over ten years ago a computer beat a chess grandmaster, but the same computer would find it incredibly difficult to pick up a chess piece.3:35
- I know, it's very strange.3:44
- But now you've reminded me that we need the answer to today's question.3:46
- Which was, what was the name of the computer which famously beat World Chess Champion Gary Kasparov in 1997?3:50
- Now you said Deep Blue Tim and that was the right answer.3:58
- You see, my educated guess was based on knowledge and experience.4:02
- Oh maybe you were just lucky.4:06
- So the IBM Supercomputer Deep Blue played against US World Chess Champion Gary Kasparov in two chess matches.4:09
- The first match was played in Philadelphia in 1996 and was won by Kasparov.4:17
- The second was played in New York City in 1997 and won by Deep Blue.4:21
- The 1997 match was the first defeat of a reigning World Chess Champion by a computer under tournament conditions.4:26
- Let's go through the words we learned today.4:34
- First up was Artificial Intelligence or AI, the ability of machines to copy human intelligent behaviour.4:37
- There are AI programs that can write poetry.4:44
- Do you have any examples you can recite?4:47
- Afraid I don't.4:50
- Number two, an algorithm is a set of steps a computer follows in order to solve a problem.4:51
