Hey, grown-ups! Did you know that spider

0:02

silk can help save the planet? And

0:05

drawing eyes on cow butts protects cows

0:07

from predators? Well you and

0:09

the curious kids in your life can learn

0:11

all about these amazing scientific

0:14

discoveries and more on the Wow

0:16

in the World podcast! The number

0:18

one podcast for curious kids and their

0:20

grown-ups, Wow in the World transforms

0:23

every car ride into a scientific

0:25

adventure! Join hosts Mindy

0:27

Thomas and Guy Raz as they

0:29

dive into the latest scientific discoveries,

0:32

innovations and stories guaranteed

0:34

to make everyone say, Wow! I'm

0:37

going to share a short clip for you now so you can get a sneak

0:39

peek at the Wow.

0:41

This clip is from a recent episode about how

0:43

AI makes art.

0:46

Let's listen.

0:56

So, just like how human artists

0:58

might go to school or university

1:01

to train to become an artist, these

1:03

AIs also have to train at

1:06

the University of the World

1:08

Wide Web.

1:09

There's a University of the World

1:11

Wide Web? Of course there's not

1:13

a University of the World Wide Web, Dennis.

1:16

Everybody is just using it as a storytelling device.

1:19

Oh, right. I knew that. Anywho,

1:22

the AI shows up for its first

1:24

year at the University of the World

1:26

Wide Web. Wow, UWWW, I

1:27

finally made it. I'm going to be the best AI art generator ever. So

1:29

in order to become a fully-fledged

1:33

AI art generator, this AI has

1:35

to first take some intro

1:45

classes.

1:45

Intro classes? Yeah,

1:48

class number one is... Object

1:52

recognition. Object recognition?

1:55

Yeah, which is exactly what it sounds like. It's

1:58

teaching the AI to recognize objects.

1:59

This is

2:02

a picture of a person throwing

2:04

a ball.

2:15

Imagine doing this for trillions

2:18

of images or pictures across

2:20

the internet. This is a picture

2:22

of a person traveling in a

2:24

ball.

2:32

Lillings of images.

2:33

It needs to learn how to

2:35

source them. Which brings us to

2:37

our second class.

2:39

Welcome to School Day 101. Yay!

2:43

Now the AI has to look through

2:46

all the images it's learned about and

2:48

source them into hundreds of different groupings.

2:52

Huh, like what? Well, take

2:54

a banana. Okay, this

2:56

is yellow. Therefore bananas

2:59

go in the yellow category.

3:03

But it sorts these pictures into hundreds of different

3:05

categories.

3:11

The banana

3:13

also goes in the long category

3:16

and also also goes

3:18

in the medium sized category and

3:21

the non-shiny category

3:24

and the fruit category. So

3:26

at the end of this class, the AI

3:28

knows both what these images are.

3:31

That is a ball. But also

3:33

the characteristics are things that make

3:36

up that image. The ball is white.

3:38

It has stitches.

3:41

It is

3:41

bright. It is used

3:44

in game and baseball. Wonderful.

3:48

You're now ready for semester two. Creation.

3:51

Yay! I finally get

3:53

to make my own art. So

3:56

now when you type a prompt into the machine...

4:00

One picture of an ice cream queen?

4:02

Hmm, okay, ice

4:05

cream, wrong, horrible,

4:09

moist, shiny. It

4:11

then ranges a bunch of pixels

4:13

into a shape that has those characteristics,

4:16

like shape, quality, and

4:19

shininess. And pixels are the

4:21

tiny dots on a screen that make

4:23

up an image. Exactly hundreds

4:26

of thousands of these little colored

4:28

dots that all come together

4:30

to make a picture. And these

4:32

AI shuffles these around based

4:34

on what it knows about the object

4:36

you asked it to generate for you. Exactly,

4:39

Doreto! Duh!

4:42

What do you think, Mrs. Teacher

4:44

Man? It's horrible! Oh

4:47

no! The first attempts are never good,

4:49

but then the AI goes away and

4:51

improves it. Moving the

4:53

pixels around just a little bit, and

4:55

it does this over and over

4:57

and over again as long as it's applying

4:59

the digits. Oh, no. No.

5:02

No. No. This

5:08

happens over and over and

5:10

over again, including little

5:13

by little until...

5:16

Oh, now that's what I call

5:18

an A plus A cream. Excellent.

5:22

Here you are, man. One picture

5:24

of A screen. I love it!

5:30

And that, Neroz, is how you train

5:32

an AI generator to become

5:34

an artist.
