Key benefits

Predict and use a probabilistic graphical models (PGM) as an expert system
Comprehend how your computer can learn Bayesian modeling to solve real-world problems
Know how to prepare data and feed the models by using the appropriate algorithms from the appropriate R package

Description

Probabilistic graphical models (PGM, also known as graphical models) are a marriage between probability theory and graph theory. Generally, PGMs use a graph-based representation. Two branches of graphical representations of distributions are commonly used, namely Bayesian networks and Markov networks. R has many packages to implement graphical models. We’ll start by showing you how to transform a classical statistical model into a modern PGM and then look at how to do exact inference in graphical models. Proceeding, we’ll introduce you to many modern R packages that will help you to perform inference on the models. We will then run a Bayesian linear regression and you’ll see the advantage of going probabilistic when you want to do prediction. Next, you’ll master using R packages and implementing its techniques. Finally, you’ll be presented with machine learning applications that have a direct impact in many fields. Here, we’ll cover clustering and the discovery of hidden information in big data, as well as two important methods, PCA and ICA, to reduce the size of big problems.

Who is this book for?

This book is for anyone who has to deal with lots of data and draw conclusions from it, especially when the data is noisy or uncertain. Data scientists, machine learning enthusiasts, engineers, and those who curious about the latest advances in machine learning will find PGM interesting.

What you will learn

Understand the concepts of PGM and which type of PGM to use for which problem
Tune the model's parameters and explore new models automatically
Understand the basic principles of Bayesian models, from simple to advanced
Transform the old linear regression model into a powerful probabilistic model
Use standard industry models but with the power of PGM
Understand the advanced models used throughout today s industry
See how to compute posterior distribution with exact and approximate inference algorithms

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.

This is an excellent introduction to the theory of probabilistic graphical models and their implementation in R. One of the hallmarks of great writing is when the author anticipates questions the reader has and provides well thought out explanations. This is the case with Bellot's book. Highly recommended!

Charles Saunders Dec 22, 2018

This is a December 2018 update - DO NOT BUY THIS OR ANY OTHER PACKT PUBLISHING BOOK UNLESS YOU CAN VERIFY THERE IS AN ERRATA FILE TO ACCOMPANY IT. PACKT PUBLISHING DOES NOT PRODUCE RELIABLE TEXTS. MY STUDENTS HAVE HAD A TERRIBLE TIME WITH PACKT BOOKS – THE COMPANY DOES RESPOND TO ANY QUESTIONS/REQUESTS - THE UNIVERSITY WHERE I TEACH IS NOW LOOKING CLOSELY AT THE VALIDITY OF THESE PUBLICATIONS.
