Environment refers to an object the agent is interacting with (e.g. The game itself in the Atari game), while the agent represents the RL algorithm 🤓 The environment starts by sending a state to the agent, which then based on its knowledge to take an action in response to that state 👍 Following that, the environment will send the agent a pair with the reward and the next state 😊 In order to update its knowledge, the environment will send a reward back to the agent. This loop continues until the environment returns a final state. [1]
The environment is a function that changes an action that was taken in the current condition into another state with a reward. Agents, on the other hand, are functions that change the state and reward to enable the agent to take the action. We can know and set the agent’s function, but in most situations where it is useful and interesting to apply reinforcement learning, we do not know the function of the environment. The environment is invisible to us, and we can only see its inputs. It’s like most people’s relationship with technology: we know what it does, but we don’t know how it works. Reinforcement learning represents an agent’s attempt to approximate the environment’s function, such that we can send actions into the black-box environment that maximize the rewards it spits out.

Reinforcement learning refers to the instruction of machine learning models in order to take a series of actions. In an unstructured, complex environment, the agent must learn how to reach a given goal. An artificial intelligence is faced with a situation similar to a game when it uses reinforcement learning. Computers use trial-and-error to find the best solution. Solution to the problem. Artificial intelligence can be given rewards or sanctions for performing the tasks it is assigned to. Its goal is to maximize the total reward.Although the designer sets the reward policy–that is, the rules of the game–he gives the model no hints or suggestions for how to solve the game. It’s up to the model to figure out how to perform the task to maximize the reward, starting from totally random trials and finishing with sophisticated tactics and superhuman skills. By leveraging the power of search and many trials, reinforcement learning is currently the most effective way to hint machine’s creativity. If a reinforcement algorithm can be run on sufficient computing power, it is possible for artificial intelligence to gain experiences from many parallel games.

Machine Learning also includes reinforcement learning. This is the act of taking appropriate action in order to maximize rewards for a given situation. Different software and devices use it to identify the optimal behaviourr for each situation. Reinforcement learning differs to supervised training in that the training data contains the answer key so the model can be trained. In reinforcement learning there is no answer, but the reinforcement agent will decide what task to accomplish. Without a data training set, the model is bound to its own experience.
