  • Greetings Professor Falken, Shall we play a game?

  • Machine learning, neural networks and deep learning are all buzzwords in AI circles.

  • But essentially theyre all referring to the attempt to teach a computer to recognize

  • a dog in any photo, or translate a language in real time, orlots of other tasks

  • To do that, engineers present a computer with a lot of data, and teach it by repetition;

  • similar to teaching an animal a trick... encourage it when it does well, and discourage it when

  • it’s wrong.

  • Eventually, the AI will get better at facial recognition or predictive text, orwhatever!

  • But the thing is, even if it can spot the dog, the computer has to do the calculation

  • every time.

  • It has to scan every pixel and check everything.

  • It can’t anticipate what you ask, it can’t realize that usually the dog is here or there

  • in the photo

  • They don’t work that way.

  • Until now.

  • Engineers atDeepMind’ -- Google’s AI system -- wanted to give their computer

  • a memory.

  • As in, the ability to remember the tasks it had done beforeand learn from its success

  • and failures on those tasks.

  • They did this insort of a funny way.

  • They taught the system to play Atari, and published a paper on their findings.

  • I love science.

  • It makes sense!

  • Video games are about learning new skills through repetition and failure.

  • You have to build on what you learned!

  • As the game progresses, requirements usually grow in complexity, and have to be combined

  • with other skills

  • All that requires memory, and the understanding of the tasks youve completed before.

  • But AI still needs lots of repetition and data to learn.

  • So, they made the computer play each game 20 million times.

  • Then, because they added the ability of the machine to remember what it did before...

  • Deepmind could apply what it learned playing Pong to playing Fishing Derby, or Kung-Fu

  • Master.

  • AI is already good at playing other games, like Go and Chess -- but it looks at the board,

  • and then calculates the best options for each move.

  • Each time.

  • Imagine if a computer could keep things in mind when learning to solve a new problem,

  • like realizing opponents trained by certain teachers would always try some special move.

  • Or more practically, realizing you always take the same route home, every day.

  • It gets a little freaky

  • Do we want machines to be able to learn?

  • To anticipate actions?

  • To be able to get set in their ways over time?

  • Bae Stephen Hawking said artificial intelligence will beeither the best, or the worst thing,

  • ever to happen to humanity.”

  • But as of now

  • AI ain’t ready.

  • It had to play those video games 20 million times.

  • Even the most hardcore Atari gamers never approached that and theyve mastered all

  • those games.

  • Over time, AI learns and then it justdoes it, but unlike life it doesn’t have the

  • ultimate motivator

  • It wasn’t programmed to die if it fails at gathering resources.

  • It wasn’t programmed to reproduce

  • It’s just a machine doing a simple, single job.

  • Even though now, AI might acquire memories, we probably shouldn’t read too much into

  • it.

  • Jerry Kaplan, a futurist and computer scientist wrote in the MIT Technology Review

  • The robots may be coming, but they are not coming for usbecause there is nothey.”

  • Machines are not people, and there’s no persuasive evidence that they are on a path

  • toward sentience.”

  • Are you still freaked out by AI?

  • Cause you shouldn’t be.

  • Watch this video right here to learn why and also let us know in the comments what you

  • think about all this stuff and come back for more episodes.
