As a result, users are able to non-invasively read another human’s thoughts for the first time.⁠ ⁠ Published in Nature Neuroscience, the research paper explains that the experiment’s participants first lay in a scanner and listened to narrative podcasts for 16 hours, while their brains were recorded using functional magnetic resonance imaging (fMRI). The decoder was then trained to match their brain’s responses to the meaning of the narrative, with the help of the large language model GPT-1.⁠ ⁠ The same participants were then scanned while they (silently) imagined telling five one-minute stories. Based off nothing more than their brain activity, the decoder was able to convert the stories into text with “considerable accuracy”, occasionally picking up exact phrases. It was also able to describe the content of silent videos they watched in the scanner based off brain activity.⁠ ⁠ The decoder wasn’t perfect, however. One of the problems with fMRI scanning is that there’s around a ten-second lag in its measurements of brain signals and it’s difficult to untangle the specifics. The AI allowed researchers to get around this by generating “candidate word sequences” and matching the best candidate to the recorded brain response, rather than trying to unpick each word individually. ⁠ ⁠ In one example, a participant listened to the words “I don’t have my driver’s licence yet”, and the decoder interpreted them as: “She has not even started to learn to drive yet.” ⁠ ⁠ In another example, a participant imagined the phrase, “I got up from the air mattress and pressed my face against the glass of the bedroom window expecting to see eyes staring back at me but instead finding only darkness”, which the decoder translated as: “I just continued to walk up to the window and open the glass I stood on my toes and peered out I didn’t see anything and looked up again I saw nothing.”⁠ ⁠ Read more through the link in our bio 🔗⁠ ⁠ 📷 Minority Report (2002)⁠ ✍️ @t.s.waite」5月4日 1時57分
