A.I. Can Track Human Bodies Through Walls Now, With Just a Wifi Signal

A new piece of software has been trained to use wifi signals — which pass through walls, but bounce off living tissue — to monitor the movements, breathing, and heartbeats of humans on the other side of those walls. The researchers say this new tech’s promise lies in areas like remote healthcare, particularly elder care, Read more about A.I. Can Track Human Bodies Through Walls Now, With Just a Wifi Signal[…]

A machine has figured out Rubik’s Cube all by itself – using a reverse technique called autodictic iteration

In these scenarios, a deep-learning machine is given the rules of the game and then plays against itself. Crucially, it is rewarded at each step according to how it performs. This reward process is hugely important because it helps the machine to distinguish good play from bad play. In other words, it helps the machine Read more about A machine has figured out Rubik’s Cube all by itself – using a reverse technique called autodictic iteration[…]
