The algorithms that are winning in games like Go or Dota 2 use reinforcement learning to train multilayer neural networks. The animal brain also uses reinforcement learning via dopamine. But research shows that the human brain performs two types of reinforcement learning on top of each other. This new theory implements a technique called Learning to Learn, also called meta-reinforcement learning, which may benefit machine learning algorithms.
