A deep neural network's ability to teach itself is a strength, because the machine gets better with experience, and a weakness, because it's got no code that an engineer can tweak. That's why the creators of Google Deep Mind's AlphaGo couldn't explain how it played the game of Go. All they could do was watch their brainchild rise from beginner status to defeat one of the best players in the world. If a robocar makes a mistake, engineers must be able to look under the hood, find the flaw and fix it so that the car never makes the same mistake again. One way to do this is through simulations that first show the AI one feature and then show it another, thus discovering which things affect decision making.
