Scientists have made new improvements to a “brain decoder” that uses artificial intelligence (AI) to convert thoughts into text.
Their new converter algorithm can quickly train an existing decoder on another person’s brain, the team reported in a new study. The findings could one day support people with aphasia, a brain disorder that affects a person’s ability to communicate, the scientists said.
A brain decoder uses machine learning to translate a person’s thoughts into text, based on their brain’s responses to stories they’ve listened to. However, past iterations of the decoder required participants to listen to stories inside an MRI machine for many hours, and these decoders worked only for the individuals they were trained on.
