If the lady in the Mona Lisa painting could talk, she could tell us why she was smiling for the pose, isn’t it? But, of course, that is not possible because she is just a painting.
However, recently, Samsung Labs in Moscow demonstrated an Al program that could create a video of a person talking just from one single profile picture. The result? A talking Mona Lisa, thanks to a technology, known as deepfake!
The word “deepfake” is a combination of the words “deep learning” and “fake”. Deep learning refers to the use of machine learning and artificial intelligence to create images of human faces. The word was used first in 2017 when an anonymous person using the name “deepfake” began to post images of celebrities’ faces on other people’s bodies.
To start with, video recordings of a person are broken down into the smallest levels of detail that capture how their mouth and facial features move when they pronounce a sound like “oo” or “ah”. These, along with the 3-D model of the lower face, are then put together and the person can be made to say words he (or she) never did.
Deepfakes use a technology called generative adversarial networks (GAN). This system uses two separate artificial intelligence systems that are trained such that one generates the images and the other attempts to tell if they are fake. The machines continue to teach each other over and over again until one produces a video that the other cannot tell it is fake!
Fake news would easily go out of hand if people believed the fake videos as real and it could have political and social effect. There is a lesson here for each of us to be careful about what we post on the Internet. In the future, you might see a picture or video of yourself and may not be able to tell that it is fake! It all just goes to show that seeing is not always believing.
1.How does the writer develop the third paragraph?
A.By defining a concept. B.By introducing an app.
C.By testing a scientific method. D.By providing different examples.
2.What can we infer about GAN from the passage?
A.It needs to be trained. B.It can learn all by itself.
C.It produces perfect pictures. D.It is used to identify fake images.
3.What is implied in the last paragraph?
A.People can use deepfakes to become famous.
B.The public aren’t easily cheated by deepfakes.
C.All of us may become a victim of deepfakes.
D.Deepfakes make what you have done known to all.
4.What is the best title for the text?
A.Mona Lisa：a Talking Picture
B.Fake Videos：Recording of a Person
C.AI Program：Creating a Video
D.Deepfakes：Believing or Not
