We all went gaga over the website which made some fake faces using the real ones that website was Thispersondoesnotexist.com. Now we see that an improved version of that website has come over with the different name: WhichFaceIsReal.com. This is the different one as it allows you to differentiate between the real and the AI generated photos. What do you think this website is made just for fun? Well! It has another motive behind it also. Jevin West and Carl Bergstrom who are the two boys behind the development of the website wanted to study how the information spreads among the society.
“When new technology like this comes along, the most dangerous period is when the technology is out there, but the public isn’t aware of it,” Bergstrom tells The Verge. “That’s when it can be used most effectively.” He added, “So what we’re trying to do is educate the public, make people aware that this technology is out there,” says West. “Just like eventually most people were made aware that you can Photoshop an image.”
GAN (Generative Adversarial Network) which is a method of machine learning has been used in the making of both the websites. This involves the examining of many real faces and then determining the pattern and after that trying to replicate whatever they have analyzed. GANs are testing themselves again and again and hence creating great results. When the photo is made, then it compares it to the training data, and if it is able to tell the difference, then the data is sent back to improve it.
“If you wanted to inject misinformation into a situation like that if you post a picture of the perpetrator and it’s someone else it’ll get corrected very quickly,” says Bergstrom. “But if you use a picture of someone that doesn’t exist at all? Think of the difficulty of tracking that down.”
