Scientists Discover AI Models May Not Think Like the Brain After All

Scientists found that AI vision models, while predicting brain responses to objects, may rely on visual strategies different from those used by the primate brain, according to a reverse prediction test. This suggests that the internal processes of these models do not necessarily match biological neural mechanisms.

A reverse prediction test suggests that supposedly brainlike AI models may rely on visual strategies the primate brain does not use. Artificial intelligence can sometimes predict how the brain responds when people recognize objects. But that resemblance may hide an important weakness: the internal workings of today’s vision models do not necessarily match the processes ...
