Human Intelligence

Reinforcement learning methods have been used by Google DeepMind, the first computer program to defeat a world champion at the ancient Chinese game of Go. Unlike supervised learning where the machine is given right and wrong answers, reinforcement learning finds the right action to optimize its "Reward" according to the state of the market. The optimal action is usually a complex function. Neural networks are a way to represent this type of function and to solve this type of complex problem.
