Look at this picture. It's a cat. You know it's a cat because you have eyes and a brain and you've seen cats before.

00:27.000 --> 00:39.000
But look. The phone knows it's a cat too. Put a little label on it. How does the phone know that?

00:39.000 --> 00:56.000
A phone doesn't have eyes. A phone doesn't have a brain. So how does it know?

00:56.000 --> 01:07.000
The answer is a kind of machine, a very, very smart machine we call it AI.

01:07.000 --> 01:15.000
AI stands for artificial intelligence. That's a big word. So we just call it AI.

01:15.000 --> 01:25.000
AI. Two letters. AI is a machine. It's not alive. It can't feel. It can't taste ice cream. But it can do something very special.

01:25.000 --> 01:44.000
It learns. Watch. We show it lots and lots of pictures of cats. Each one is called an example. And the more examples it sees, the smarter it gets.

01:44.000 --> 01:52.000
AI can spot a cat in a new picture it has never seen before. So AI is a machine that learns from examples.

01:52.000 --> 02:08.000
Three words. Say them with me. Machine. Learns. Examples.

02:08.000 --> 02:17.000
But here's a secret. How does the machine actually learn? What's happening inside?

02:22.000 --> 02:36.000
We don't tell you yet. That's a secret for next time. We meet that secret tomorrow. See you then.
