AI "读心" 工具通过脑部扫描重建图像
科学家开发出一种AI工具，可以通过脑部扫描重建人们看到的图像，在帮助Locked-in患者沟通和理解大脑工作原理方面具有潜在应用价值。
a team led by michal irani at the weizmann institute of science developed an ai 'mind-reading' tool that can reconstruct images seen by a person based on their brain scans. the tool was trained on data from eight people who were shown around 9,000 images while in a high-resolution fMRI scanner. it uses a diffusion model and has two branches to predict the structure and content of an image. while it has potential applications in helping locked-in people communicate and understanding how the brain works, other scientists warn that similar approaches could be used to reveal inner thoughts and mental imagery without consent.
