-
Which of these three faces do you think is the oldest?
-
A, B or C?
-
The answer is actually none of them, because none of these people were ever born.
-
These faces were all generated by artificial intelligence.
-
Now, thinking about artificial intelligence, look carefully at these two paintings.
-
Which of these does your mind think is created by AI?
-
Is it painting A or painting B?
-
Give up?
-
The clue is in the signature.
-
The AI seems a bit busted on this one.
-
But someone loved it as it went at an auction for $432,500.
-
To explain how these images are generated, let's first look at these images of fruit.
-
By now, you know that one isn't real, but is it the apples or the oranges?
-
If you said apples, you're right!
-
Essentially, a system is fed hundreds of images to learn from.
-
It's then split into two systems.
-
System 1's job is to create a convincing image of an apple,
-
and system 2 is designed to figure out which images of apples are fake.
-
This is known as a generative adversarial network.
-
If system 1 fails at tricking, it continues to evolve its apple designing skills,
-
and if system 2 fails at identifying the fake, it must also improve its ability to catch a fake.
-
This ultimately creates a feedback loop that generates extremely believable images.
-
Now, let's try to relax and listen to some music while you try to deduce which is composed by a computer.
-
Turns out that composition A is generated by a machine learning system called Emily Howell,
-
which was created in the 90s and learned from a library of music to create original pieces.
-
And composition B?
-
That's by Johann Sebastian Bach.
-
A larger library of music will give the machine learning networks more data to learn from, and the same is true for video.
-
Because we upload such huge amounts of video content online,
-
neural networks have begun to create convincing fake videos.
-
Here's a video of the 44th President of the United States, Barack Obama.
-
People not trapped by our past, but able to remake ourselves as we choose.
-
But today, our immigration system is broken, and everybody knows it.
-
And here's another.
-
It's been less than a week since the deadliest mass shooting in American history.
-
And foremost in all of our minds has been the loss and the grief felt by the people of Orlando.
-
Which of these two are real?
-
Video A or B?
-
Known as a deep fake video, video B is generated using AI.
-
With over 14 hours of footage from the president's weekly addresses, neural network AI is able to model the shape of Obama's mouth,
-
and uses audio from one of Obama's previous addresses.
-
But can AI generate convincing synthetic audio?
-
Listen to this phone call.
-
How can I help you?
-
Hello?
-
Hello, what's up, man?
-
Hey, um, I wanted to know what are your hours for today?
-
10 a.m. to 6:30 p.m.
-
Okay.
-
Got it.
-
Thank you for your time.
-
No problem sir.
-
Bye.
-
Can you tell which of the callers is human?
-
Voice B, the voice you hear asking about the hours the business was open, was fake.
-
We're relying more and more on technology today, which is making our lives easier.
-
Much like SimpliSafe, the sleek new home security system who sponsored today's video.
-
We bought a house recently and finally realized what it feels like to go anywhere and be like, okay legit we're probably gonna be robbed right now, and the stats are in.
-
America has a robbery every 15 seconds, most of which happen while you're at work.
-
So join our new zen life by going to simplisafe dot com slash asap and ease your mind.
-
Importantly for us in our new pad is that it looks cute.
-
The design is awesome, it's intuitive to set up and use, you barely notice the sensors are there,
-
and we like that it does cool things like remind you if you left the door open because Gregg literally does that all the time.
-
He leaves the door wide open when he leaves.
-
In the event of an actual break-in, it can immediately contact the police.
-
We literally just set up our own at home, and it's just one of those things where you get like peace of mind knowing that it's there for you.
-
And it can even tell the difference between a pet and an intruder!
