Physicists have discovered what makes neural networks so extraordinarily powerful

Nobody understands why deep neural networks are so good at solving complex problems. Now physicists say the secret is buried in the laws of physics. In the last couple of years, deep learning techniques have taken the world of artificial intelligence by storm. One by one, the abilities and techniques that humans once imagined were uniquely our own have begun to fall to the onslaught of ever more powerful machines. Deep neural networks are now better than humans at tasks such as face recognition and object recognition.
