It already seems a little like computers can read our minds; features like Google’s auto-complete, Facebook’s friend suggestions, and the targeted ads that appear while you’re browsing the web sometimes make you wonder, “How did they know?” For better or worse, it seems we’re slowly but surely moving in the direction of computers reading our minds for real, and a new study from researchers in Kyoto, Japan is an unequivocal step in that direction.
A team from Kyoto University used a deep neural network to read and interpret people’s thoughts. Sound crazy? This actually isn’t the first time it’s been done. The difference is that previous methods—and results—were simpler, deconstructing images based on their pixels and basic shapes. The new technique, dubbed “deep image reconstruction,” moves beyond binary pixels, giving researchers the ability to decode images that have multiple layers of color and structure.
