How does it work?

This is a bit similar to the traditional type of data analysis; the algorithm discovers through trial and error and decides which action results in greater rewards. Three major components can be identified in reinforcement learning functionality: the agent, the environment, and the actions. The agent is the learner or decision-maker, the environment includes everything that the agent interacts with, and the actions are what the agent can do. Reinforcement learning occurs when the agent chooses actions that maximize the expected reward over a given time. This is best achieved when the agent has a good policy to follow.

Control-based: When running a Reinforcement Learning (RL) policy in the real world, such as controlling a physical robot on visual inputs, it is non-trivial to properly track states, obtain reward signals or determine whether a goal is achieved for real. The visual data has a lot of noise that is irrelevant to the true state and thus the equivalence of states cannot be inferred from pixel-level comparison. Self-supervised representation learning has shown great potential in learning useful state embedding that can be used directly as input to a control policy.

Reinforcement learning is an area of machine learning that involves taking right action to maximize reward in a particular situation. In this full tutorial course, you will get a solid foundation in reinforcement learning core topics. The course covers Q learning, State-Action-Reward-State-Action (SARSA), double Q learning, Deep Q Learning (DQN), and Policy Gradient (PG) methods. These algorithms are employed in a number of environments from the open AI gym, including space invaders, breakout, and others. The deep learning portion uses Tensorflow and PyTorch. The course begins with more modern algorithms, such as deep q learning and Policy Gradient (PG) methods, and demonstrates the power of reinforcement learning. Then the course teaches some of the fundamental concepts that power all reinforcement learning algorithms. These are illustrated by coding up some algorithms that predate deep learning, but are still foundational to the cutting edge. These are studied in some of the more traditional environments from the OpenAI Gym, like the cart pole problem.
