A high-level overview of Reinforcement Learning modelsPhoto by Kelly Sikkema on UnsplashReinforcement learning is the fourth major learning method in machine learning, along with supervised, unsupervised, and semi-supervised learning. The main difference is that the model does not need any data to train. It learns structures by being rewarded for desired behaviors and punished for bad ones.Before we can look in detail at what the training process looks like for such models, we should understand in which situations these…
