The first foundations of AI were built more than 50 years ago, but only in the last few years has the innovation brought by AI spread through the world as a mainstream technology. This new wave of innovation is mainly due to the evolution of deep neural networks in supervised learning systems. However, the most recent breakthrough in artificial intelligence involves reinforcement learning, and most notably, deep reinforcement learning. Results like the ones that were obtained in the game of Go and Dota highlight the impressive quality of RL algorithms that are able to show long-term planning, ability in teamwork, and discover new game strategies that are difficult to comprehend even for humans.
The remarkable results that were obtained in the simulated environments started a new wave of applications of reinforcement learning in the physical...
