This artificial intelligence can see humans through walls

Artificial intelligence has been taught to see people through walls, using nothing more than a radio signal 1,000 times weaker than Wi-Fi. Developed by a team of researchers at the Massachusetts Institute of Technology (MIT), the system can see the basic stick-person outline of human through a wall. It can do so with almost the same accuracy whether the wall is there or not. MIT's Computer Science & Artificial Intelligence Lab said: "The researchers use a neural network to analyze radio signals that bounce off people's bodies, and can then create a dynamic stick figure that walks, stops, sits, and moves its limbs as the person performs those actions." Called RF-Pose, the system works because radio frequencies pass through walls but reflect off humans, revealing their location in a similar way to how radar and lidar systems work.
