AI that can read people's minds: it could be a revolution

Scientists have created a system that allows them to read people's minds. Fortunately, it still can't be done from a distance - for it to work, a person must wear a helmet with sensors connected to artificial intelligence.

This is stated in a study reported by New Scientist. "The resulting system is able to convert thoughts into text with an accuracy of over 60%.

In the study, participants read passages of text while wearing a helmet with sensors that recorded electrical activity in the brain through the scalp. Subsequently, these electroencephalogram (EEG) recordings were converted into text using an artificial intelligence model called DeWave.

The advantage of this technology, as explained by Chin-Teng Lin from the University of Technology Sydney (Australia), is that it is non-invasive, relatively inexpensive, and easily transportable.

The first studies of the scientists gave an accuracy of decoding thoughts at the level of about 40%, but further tests improved the accuracy of the system, raising it to 60%.

The scientists said that the system works both when the subject reads the text aloud and when he reads it silently. The DeWave model has been trained to match brain signals with specific words and sentences using numerous examples.

"For example, when you think about saying 'hello,' your brain sends certain signals. DeWave learns how these signals are related to the word 'hello' by seeing many examples of these signals for different words and sentences," Zhou explained.

Once DeWave had a sufficient database of brain signals, the scientists connected it to a large language model (LLM), similar to the artificial intelligence that runs ChatGPT. This LLM is similar to a writer who composes sentences by analyzing brain signals decoded by DeWave.

Researchers believe that improving the system could revolutionize communication for people who have lost their speech, for example, after a stroke.

Last year, scientists from the United States achieved similar success, but their system for converting thoughts into text required that the subject stay motionless in an MRI scanning machine. Thus, the use of EEG for "mind reading" is more practical.
