Reinforcement learning has become a trending topic among all the tech giants and none of them is sitting back to catch up on this. OpenAI Baselines is a set of high-quality implementations of reinforcement learning algorithms. These algorithms make it easier for the research community to replicate, refine, and identify new ideas to create good baselines to build research on top of. They have beautifully abstracted the details of the RL algorithms and have made the use of these techniques as easy as calling a single class and feeding it essential details like environment name and batch sizes. This has made experimentation much easier and implementation simpler for the people new to the field.
