Reinforcement Learning: An Introduction. Second edition, in progress. **** Complete Draft****. November 5, Richard S. Sutton and Andrew G. Barto c Reinforcement Learning: An Introduction. Small book cover. Richard S. Sutton and Andrew G. Barto. Second Edition (see here for the first edition) MIT Press. We first came to focus on what is now known as reinforcement learning in late. We were both at the University of Massachusetts, working on one of.

Their discussion ranges from the history of the field's intellectual foundations to the most recent developments and applications. Reinforcement learning, one of the most active research areas in artificial intelligence, is a computational approach to learning whereby an agent tries to maximize the total amount of reward it receives when interacting with a complex, uncertain environment. In Reinforcement Learning, Richard Sutton and Andrew Barto provide a clear and simple account of the key ideas and algorithms of reinforcement learning. The only necessary mathematical background is familiarity with elementary concepts of probability. The book is divided into three parts.

Trajectory: A sequence of states and actions that influence those states. So environments are functions that transform an action taken in the current state into the next state and a reward; agents are functions that transform the new state and reward into the next action. It is a black box where we only see the inputs and outputs. Unlike other forms of machine learning — such as supervised and unsupervised learning — reinforcement learning can only be thought about sequentially in terms of state-action pairs that occur one after the other.

Reinforcement learning judges actions by the results they produce. It is goal oriented, and its aim is to learn sequences of actions that will lead an agent to achieve its goal, or maximize its objective function. In the real world, the goal might be for a robot to travel from point A to point B, and every inch the robot is able to move closer to point B could be counted like points.

We are summing reward function r over t, which stands for time steps. So this objective function calculates all the reward we could obtain by running through, say, a game.

Here, x is the state at a given time step, and a is the action taken in that state. Reinforcement learning differs from both supervised and unsupervised learning by how it interprets inputs. Labels, putting names to faces… These algorithms learn the correlations between data instances and their labels; that is, they require a labelled dataset. Reinforcement learning: Eat that thing because it tastes good and will keep you alive longer.

Actions based on short- and long-term rewards, such as the amount of calories you ingest, or the length of time you survive. Reinforcement learning can be thought of as supervised learning in an environment of sparse feedback.

Domain Selection for Reinforcement Learning One way to imagine an autonomous reinforcement learning agent would be as a blind person attempting to navigate the world with only their ears and a white cane.

In fact, deciding which types of input and feedback your agent should pay attention to is a hard problem to solve. This is known as domain selection. Algorithms that are learning how to play video games can mostly ignore this problem, since the environment is man-made and strictly limited. Thus, video games provide the sterile environment of the lab, where ideas about reinforcement learning can be tested. Domain selection requires human decisions, usually based on knowledge or theories about the problem to be solved; e.

Since those actions are state-dependent, what we are really gauging is the value of state-action pairs; i. We map state-action pairs to the values we expect them to produce with the Q function, described above. Reinforcement learning is the process of running the agent through sequences of state-action pairs, observing the rewards that result, and adapting the predictions of the Q function to those rewards until it accurately predicts the best path for the agent to take.

That prediction is known as a policy. Reinforcement learning is an attempt to model a complex probability distribution of rewards in relation to a very large number of state-action pairs. This is one reason reinforcement learning is paired with, say, a Markov decision process , a method to sample from a complex distribution to infer its properties.

It closely resembles the problem that inspired Stan Ulam to invent the Monte Carlo method ; namely, trying to infer the chances that a given hand of solitaire will turn out successful. Any statistical approach is essentially a confession of ignorance. The immense complexity of some phenomena biological, political, sociological, or related to board games make it impossible to reason from first principles. The only way to study them is through statistics, measuring superficial events and attempting to establish correlations between them, even when we do not understand the mechanism by which they relate.

Reinforcement learning, like deep neural networks, is one such strategy, relying on sampling to extract information from data. After a little time spent employing something like a Markov decision process to approximate the probability distribution of reward over state-action pairs, a reinforcement learning algorithm may tend to repeat actions that lead to reward and cease to test alternatives.

There is a tension between the exploitation of known rewards, and continued exploration to discover new actions that also lead to victory. Reinforcement learning is iterative. It learns those relations by running through states again and again, like athletes or musicians iterate through states in an attempt to improve their performance.

The Relationship Between Machine Learning with Time You could say that an algorithm is a method to more quickly aggregate the lessons of time.

An algorithm can run through the same states over and over again while experimenting with different actions, until it can infer which actions are best from which states.

Effectively, algorithms enjoy their very own Groundhog Day , where they start out as dumb jerks and slowly get wise.

The main differences are: The most difficult sections are clearly marked as such, and can be skipped. But taking on the difficulties straight on is always positively rewarding, in the end. Many exercises are included. I am no math buff and found that I could do every single one of them on my own, which is unfortunately not usually the case in other A.

These exercises serve to help the reader understand key issues by working them out for themselves, in a guided manner; they make self-study possible and enjoyable. This is an indispensable book for anybody working in RL.

My only issue is that I'm too late to be referenced in it, but I haven't lost hope of making it in the 3rd edition, which is expected in This book would barely pass as an EE version of a textbook. The spine feels like it's made of cheap cardboard and is not straight not does it cover all the pages.

The covers are shorter than the pages. The spine bends over backwards when I pick up the book. The pages are not straight. The print quality is extremely low. I don't know how this happened but I am returning asap and will try to find an official copy of this book. Compared to Kindle version, printed version: Contains figures of low-resolution with blurred colors: Pages contain paper defects 4.

Looks like a fake print, definitely not from MIT Press. Book quality is so low, chapter 3 and 4 are repeated twice and only first 7 page of each chapter is in the book.
