The application of artificial intelligence in reading human thoughts is constantly evolving. In this case, they trained the AI to find faces that you think are truly attractive.You may not even know how to describe
Beauty exists in everyone’s brain, with its subjectivity and preferences. They have trained artificial intelligence to detect your taste and shape it to generate a particularly beautiful face.
In this case, their achievement is to extract the most attractive faces and their preferences from the depths of the thoughts of the experimental volunteers. What is disturbing is that artificial intelligence makes your taste beyond what you can describe. The disadvantage is that these people do not exist.
Artificial intelligence is generated using data extracted from the faces of male and female volunteers, and after displaying them in other photos, the faces generated by artificial intelligence are selected by each object as the most beautiful face.
This work was carried out by researchers from the University of Helsinki and the University of Copenhagen and has been published in Emotional calculation.
They first randomly generate faces until they create something similar to the Tinder Contacts application. The second step is to show these faces to the experimental volunteers as they read their brain waves. In this way, they manage to “observe” reactions that can only be experienced when you observe the brain from the inside, because in many cases they are unconscious.
Attraction is a challenging research topic because it is related to cultural and psychological factors, which may play a subconscious role in our personal preferences. In fact, it is often difficult for us to explain exactly what makes someone or someone truly beautiful: what is beauty in the eyes of a lover,” said the chief researcher and faculty. Michelle Spapé (MichielSpapé) Department of Psychology and Speech Therapy, University of Helsinki.
What does your brain like more
The researchers initially asked the neural network to create hundreds of artificial portraits. The images were shown to 30 volunteers who were asked to pay attention to the attractive faces they found while recording their brain responses using electroencephalography (EEG).
“It works a bit like the dating app Tinder: Participants will “swipe to the right” when they encounter attractive faces. However, here, they don’t need to do anything other than viewing the images. Spapé explained that we They measured their direct brain responses to the images.
Researchers used machine learning technology to analyze the EEG data, and connect each EEG data to the generating neural network through a brain-computer interface.
A brain-computer interface like this can explain the user’s perception of the attractiveness of various images. By explaining their point of view, the AI model that explains the brain’s response and the generative neural network that model the facial image can jointly generate a new facial image by combining the attractiveness of a specific person. ”Associate Professor Tuukka Ruotsalo , Who is in charge of the project.
To test the effectiveness of the model, the researchers generated new portraits for each participant and predicted that they would be more attractive than others. After testing it through a double-blind program, they found that the new image fits the subject’s preferences with an accuracy rate of over 80%.
Spapé explained: “We proved that it is possible to detect and generate images based on psychological characteristics (such as personal taste).”
Does artificial intelligence know you better than you?
“If we do this between personal charm and subjective charm, we can also analyze other cognitive functions, such as perception and decision-making. Potentially, Spapé said, we can guide the device to recognize implicit stereotypes or prejudices, and more Understand individual differences well.
