Experts say computers in the future could be able to read your mind, making everything from online dating to video games a lot easier.

Artificial intelligence (AI) can figure out who you’re attracted to. A computer program could generate images of faces that it knew certain users would find attractive by examining brain scans. It’s part of a growing effort to build computers that can understand our thoughts.

“Such a system can be used to select the content to be presented to a particular user,” Radek Kamiński, CEO of nexocode, a company focused on AI implementation and consulting, said in an email interview. “For example, we will likely see personalized ads with both content and presentation optimized based on implicit and explicit signals collected from you.”

The AI, developed by a team from the University of Helsinki and the University of Copenhagen, is designed to generate fake photos of faces. The researchers trained the system on 200,000 celebrity images shown to 30 study participants, whose brain activity was monitored using electroencephalography, a method of measuring electrical signals in the brain. There was an increase in brain activity when participants were shown an image of a face they found attractive.
