But doing such things as passing under the eaves of houses, you still get wet. When you are resolved from the beginning, you will not be perplexed, though you will still get the same soaking. This understanding extends to everything.”

Concepts to Understand Reinforcement Learning
In which I explain what is reinforcement learning, where it fits in the whole as a machine learning paradigm. Some of the basic concepts of reinforcement how they interact with each other and some possible directions. Introduction Reinforcement learining — RL — seems to be the hot topic in machine learning nowadays, it’s the basis for the algorithm that beat the Go champion, a game in which, pundits claim, a computer would not be able to beat a human within this century and also it is what makes you spend more when shopping online.
