Researchers revealed as we speak that they’ve demonstrated how an A.I. can primarily “learn minds” by analyzing fMRI mind scans and translating that data into phrases reflecting the personal ideas of the human topic.

“This is not only a language stimulus,” mentioned Alexander Huth, a neuroscientist on the college who helped lead the analysis. “We’re getting at which means, one thing in regards to the thought of what is occurring. And the truth that that is attainable could be very thrilling.” […]

This language-decoding technique had limitations, Dr. Huth and his colleagues famous. For one, fMRI scanners are cumbersome and costly. Furthermore, coaching the mannequin is an extended, tedious course of, and to be efficient it have to be carried out on people. When the researchers tried to make use of a decoder skilled on one particular person to learn the mind exercise of one other, it failed, suggesting that each mind has distinctive methods of representing which means.
