Google’s artificial intelligence technology may sometimes seem like it’s reading our mind, but neuroscientists at Canada’s University of Toronto Scarborough are literally using A.I. for that very purpose — by reconstructing images based on brain perception using data gathered by electroencephalography (EEG).
In a test, subjects were hooked up to EEG brainwave-reading equipment and shown images of faces. While this happened, their brain activity was recorded and then analyzed using machine learning algorithms. Impressively, the researchers were able to use this information to digitally re-create the face image stored in the person’s mind. Unlike basic shapes, being able to re-create faces involves a high level of fine-grained visual detail, showcasing a high level of sophistication for the technology.
While this isn’t the first time that A.I. has been used to read people’s minds, it’s the first time this has been achieved using EEG data. Previous studies involved fMRI technology, which measures brain activity by detecting changes in its blood flow. One of the most exciting differences between the two techniques is that EEG is far more portable, inexpensive, and can deliver greater levels of detail in mere milliseconds.
