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.
*bruh*
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.
[Track A]
[Track B]
Turns out that composition A is generated by a machine learning system called Emily Howell,
which was created in the 90's 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.
[Video A] People not trapped by our past, but able to remake ourselves as we choose.
[Video A] But today, our immigration system is broken, and everybody knows it.
and here's another.
[Video B] It's been less than a week since the deadliest mass shooting in American history.
[Video B] 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.
[Voice A] How can I help you?
[Voice B] Hello?
[Voice A] Hello, what's up, man?
[Voice B] Hey, um, I wanted to know what are your hours for today?
[Voice A] 10 a.m. to 6:30 p.m.
[Voice B] Okay. Got it. Thank you for your time.
[Voice A] No problem sir.
[Voice B] 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.com/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!
So go to simplisafe.com/asap to get yours today and make sure you subscribe for more videos every Thursday.
