The topic of this book is Reinforcement Learning—which is a
subfield of Machine Learning—focusing on the general and
challenging problem of learning optimal behavior in complex
environment. The learning process is driven only by reward value
and observations obtained from the environment. This model is very
general and can be applied to many practical situations from playing
games to optimizing complex manufacture processes.
Due to flexibility and generality, the field of Reinforcement Learning
is developing very quickly and attracts lots of attention both from
researchers trying to improve existing or create new methods, as well
as from practitioners interested in solving their problems in the most
efficient way.
This book was written as an attempt to fill the obvious lack of
practical and structured information about Reinforcement Learning
methods and approaches. On one hand, there are lots of research
activity all around the world, new research papers are being
published almost every day, and a large portion of Deep Learning
conferences such as NIPS or ICLR is dedicated to RL methods. There
are several large research groups focusing on RL methods application
in Robotics, Medicine, multi-agent systems, and others. The
information about the recent research is widely available, but is too
specialized and abstract to be understandable without serious efforts.
Even worse is the situation with the practical aspect of RL
application, as it is not always obvious how to make a step from the
abstract method described in the mathematical-heavy form in a
research paper to a working implementation solving actual problem.
This makes it hard for somebody interested in the field to get an
intuitive understanding of methods and ideas behind papers and
conference talks. There are some very good blog posts about various
RL aspects illustrated with working examples,
