The site’s concept has been the focus of two academic studies that analyzed artificial intelligence, as well as social behavior, in dating apps.
“The neural network itself then learns what parts of the face to look at. Visualizations showed that the neural network tends to focus on parts of the face that are “non-standard,” i.e. if you have beautiful eyes, a large nose, no hair, a sexy beard,” Zimmermann said. A similar strategy was used to guess people’s ages — wrinkles, for example.
