Artificial intelligence can speed-sort satellite photos

In 1957 Frank Rosenblatt, a psychologist, built a machine called the Perceptron. Modelled on the human brain, its neural networks were a forerunner of today’s artificial intelligence (ai). It intrigued the cia which was drowning in photos from spy planes and satellites. It funded the Perceptron in the hope of automatically identifying objects of interest. The experiment failed. There was not enough computing power, storage or training data available. But it was a start.
