Images from a possible future have been experienced by researchers at the University of Pennsylvania. The question that they asked and tried to answer was whether in the future artificial intelligence could not only read a man’s mind, but also make a video of what he was seeing. Surely this will not happen soon, but the first steps have just begun.
A team of researchers, who published a publication in the journal Cerebral Cortex, according to Science, created an artificial intelligence system whose algorithms can partially guess what the human mind thinks and then try to convert their thoughts in pictures.
Researchers, headed by the Chinese-based assistant professor Zongming Liu of the University of Pennsylvania, University of Electrical and Computer Engineering and Biomedical Engineering, placed three women to watch hundreds of videos and at the same time a functional magnetic tomography (fMRI) recorded their brain activity.
At the same time, a convolutive neural network of deep learning and image processing learned to associate images with women’s brain patterns. From one point onwards, the artificial intelligence system could only predict what volunteers were seeing and, based on this assessment, the researchers were able to make a rough picture of the brain’s content.
So far, the system – by analyzing brain activity – has a success rate of about 50% (ie it falls within half the time) in guessing what a person is seeing and what his brain is doing, choosing between 15 categories of objects and activities (bird, airplane, physical exercise, etc.).
If the artificial intelligence system has been trained to data by a woman but tried to guess the brain content of another woman, then its success rate drops to 25% (one in four). The system has already begun to reproduce the image of what a person has in his brain, but for the moment the static images are like “splashes” of pixels.
But researchers believe the system will progress along the path, and will once be able to “translate” thoughts or even dreams into digital computer data and eventually into video tapes. In other words, the ultimate goal is to create science fiction machines that will read and display our minds on a screen! But this will not be easy at all, because the mind of man is an abyss …
