An introduction to Reinforcement Learning – freeCodeCamp

Reinforcement learning is an important type of Machine Learning where an agent learn how to behave in a environment by performing actions and seeing the results. In recent years, we've seen a lot of improvements in this fascinating area of research. Examples include DeepMind and the Deep Q learning architecture in 2014, beating the champion of the game of Go with AlphaGo in 2016, OpenAI and the PPO in 2017, amongst others. In this series of articles, we will focus on learning the different architectures used today to solve Reinforcement Learning problems. These will include Q -learning, Deep Q-learning, Policy Gradients, Actor Critic, and PPO.
