Keras Reinforcement Learning Projects

Simulating Random Walks

Stochastic processes involve systems that evolve over time (but also more generally in space) according to probabilistic laws. Such systems or models describe the complex phenomena of the real world that have the possibility of being random. These phenomena are more frequent than we can believe. We encounter these phenomena when the quantities we are interested in are not predictable with absolute certainty. However, when such phenomena show a variability of possible outcomes that can be somehow explained or described, then we can introduce a probabilistic model of the phenomenon.

For example, say that we are examining the motion involved in a random walking movement. We study the motion of an object that is constrained to move along a straight line in the two directions allowed. At each movement, it moves randomly to the right or left, each step being...

Random walks

Random walks are a mathematical model that is used to describe a path that is given by a succession of random steps, which, depending on the system that we want to describe, may have a certain number of degrees of freedom or direction. The term random walk was introduced by Karl Pearson in 1905. In a random walk, each step has a random direction and possibly also a random dimension. It represents a theoretical model to describe any random process through the evolution of known quantities that follow a precise statistical distribution. Physically speaking, the path that we are going to draw over time will not necessarily describe a real motion, but rather indicate more generally the evolution of features over time. This means that random walks find applications in physics, chemistry, and biology, but also in other fields, such as computer science, economics, and sociology...

Markov chains

A Markov chain is a mathematical model of a random phenomenon that evolves over time in such a way that the past influences the future only through the present. The time can be discrete (a whole variable), continuous (a real variable), or, more generally, a totally ordered whole. In this discussion, only discrete chains are considered. Markov chains were introduced in 1906 by Andrei Andreyevich Markov (1856–1922), from whom the name derives.

The example of a one-dimensional random walk seen in the previous section is a Markov chain; the next value in the chain is a unit that is more or less than the current value with the same probability of occurrence, regardless of the way in which the current value was reached.

Summary

In this chapter, we looked at stochastic processes and their applications. We looked at starting a random walk model. Random walks are mathematical models that are used to describe a path given by a succession of random steps, which, depending on the system we want to describe, may have a certain number of degrees of freedom or direction. We have learned how to deal with one-dimensional random walks, and we have seen how to write a code for the simulation of a random walk in the Python language.

Then we were introduced to Markov chains. To understand this topic, you were briefly introduced to probability calculation. The a priori probability, joint probability, and conditional probability were all defined, with examples of their calculation. We then moved on to the definition of Markov chains. A Markov chain is a mathematical model of a random phenomenon that evolves over...

Description

Reinforcement learning has evolved a lot in the last couple of years and proven to be a successful technique in building smart and intelligent AI networks. Keras Reinforcement Learning Projects installs human-level performance into your applications using algorithms and techniques of reinforcement learning, coupled with Keras, a faster experimental library. The book begins with getting you up and running with the concepts of reinforcement learning using Keras. You’ll learn how to simulate a random walk using Markov chains and select the best portfolio using dynamic programming (DP) and Python. You’ll also explore projects such as forecasting stock prices using Monte Carlo methods, delivering vehicle routing application using Temporal Distance (TD) learning algorithms, and balancing a Rotating Mechanical System using Markov decision processes. Once you’ve understood the basics, you’ll move on to Modeling of a Segway, running a robot control system using deep reinforcement learning, and building a handwritten digit recognition model in Python using an image dataset. Finally, you’ll excel in playing the board game Go with the help of Q-Learning and reinforcement learning algorithms. By the end of this book, you’ll not only have developed hands-on training on concepts, algorithms, and techniques of reinforcement learning but also be all set to explore the world of AI.

I hate writing less than positive reviews, but this - not cheap - book, initially excited me and then disappointed.The title of the book is a little misleading too. Keras didn't really get used until almost half way through. Before hand it seems to be over complicated explanation and Python code examples.The stock price prediction example was very light weight and perhaps a missed opportunity?Some text seems to be repeated more than necessary also.The code examples ( downloadable ) generally worked first time.The Gym libraries were 'nice' but just goto their website and it's all there.The line-by-line code explanations were ok, but I would have preferred code with comments ( there were none ? ) and a more generic explanation.I didn't really feel I could take the '9 projects' and apply them usefully. Sorry.A brave attempt, but overly wordy, with some ok examples but nothing I feel I can usefully take forward into the real world.I didn't feel 'equipped'.Maybe you will think differently?!

Lo cierto es que no es un libro tan práctico como prometía ser. Contiene algo de código de keras, y lo explica y comenta todo línea a línea, lo cual está muy bien. Pero los ejemplos son justitos, y tiene la manía de irse por los cerros de Úbeda, explicando por ejemplo lo que es un robot, o explicando teoría de juegos y tipos de juegos de mesa. Esto está muy bien, pero no es lo que yo buscaba con este libro. Es una mezcla entre cultura general, y un poco de práctica.
