Key benefits

Discover various GAN architectures using a Python and Keras library
Understand how GAN models function with the help of theoretical and practical examples
Apply your learnings to become an active contributor to open source GAN applications

Description

Generative Adversarial Networks (GANs) have revolutionized the fields of machine learning and deep learning. This book will be your first step toward understanding GAN architectures and tackling the challenges involved in training them. This book opens with an introduction to deep learning and generative models and their applications in artificial intelligence (AI). You will then learn how to build, evaluate, and improve your first GAN with the help of easy-to-follow examples. The next few chapters will guide you through training a GAN model to produce and improve high-resolution images. You will also learn how to implement conditional GANs that enable you to control characteristics of GAN output. You will build on your knowledge further by exploring a new training methodology for progressive growing of GANs. Moving on, you'll gain insights into state-of-the-art models in image synthesis, speech enhancement, and natural language generation using GANs. In addition to this, you'll be able to identify GAN samples with TequilaGAN. By the end of this book, you will be well-versed with the latest advancements in the GAN framework using various examples and datasets, and you will have developed the skills you need to implement GAN architectures for several tasks and domains, including computer vision, natural language processing (NLP), and audio processing. Foreword by Ting-Chun Wang, Senior Research Scientist, NVIDIA

Mike H. May 29, 2019

The book holds promise but suffers from several major issues. First of all is the quality is the editorial. This author LOVES their commas. They use what seems like an average of three commas per sentence making those sentences unnecessarily long and often difficult to follow.My other complaint is that the beginning of the book states, in several places, that you only need a general, rudimentary understanding of python as a prerequisite, then launches into graduate level mathematics throughout the entire first half of the book. There is only an exceedingly brief overview of introductory NN concepts like in other books I've read, not enough for someone just starting out to grasp the concepts. This sort of negates the author's insistence in the beginning that you don't need much experience or advanced education in the field to understand the concepts presented.None of the information provided in the book is immediately applicable and it is written for the most part as if lifted straight out of an academic journal. So much of this book is written like that: terribly academic, boring to read, hard to follow, and not as practical as others in this subject (I've read over a dozen on this topic alone).There are also several misprints leading to certain formulas being unreadable and several typos I've found in the text. The code examples are not the easiest to follow compared to other books, even for an experienced developer like myself, because of the way they are presented and described (most of the time there is actually very little explanation as to what is going on in the code). For example, there is no (or very little) description as to why certain things are handled and instantiated in a certain way as presented.Lastly, the graphs and images reference colors in certain segments but they are all printed in black and white - this is a common problem with books published by Pact I've found and not necessarily the author's fault.Overall, it is a hard book to get through, even for this type of material which can be very technical. It is dry, formulaic, academic, and not nearly as practical or easy to follow as others I've read. It feels more like a graduate thesis sometimes than a practical resource for developers and people just starting out in this field. There are far better, and more practical, options available out there for those of you who haven't yet completed a Master's degree in mathematics.

0 Stars.I expected I would learn how to build my own model.You only use the examples from GitHub, and these don't work.

What are credits?

Credits can be earned from reading 40 section of any title within the payment cycle - a month starting from the day of subscription payment. You also earn a Credit every month if you subscribe to our annual or 18 month plans. Credits can be used to buy books DRM free, the same way that you would pay for a book. Your credits can be found in the subscription homepage - subscription.packtpub.com - clicking on ‘the my’ library dropdown and selecting ‘credits’.

What happens if an Early Access Course is cancelled?

Projects are rarely cancelled, but sometimes it's unavoidable. If an Early Access course is cancelled or excessively delayed, you can exchange your purchase for another course. For further details, please contact us here.

Where can I send feedback about an Early Access title?

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I am a Packt subscriber, do I get Early Access?

Yes, all Early Access content is fully available through your subscription. You will need to have a paid for or active trial subscription in order to access all titles.

How is Early Access delivered?

Early Access is currently only available as a PDF or through our online reader. As we make changes or add new chapters, the files in your Packt account will be updated so you can download them again or view them online immediately.

How do I buy Early Access content?

Early Access is a way of us getting our content to you quicker, but the method of buying the Early Access course is still the same. Just find the course you want to buy, go through the check-out steps, and you’ll get a confirmation email from us with information and a link to the relevant Early Access courses.

What is Early Access?

Keeping up to date with the latest technology is difficult; new versions, new frameworks, new techniques. This feature gives you a head-start to our content, as it's being created. With Early Access you'll receive each chapter as it's written, and get regular updates throughout the product's development, as well as the final course as soon as it's ready.We created Early Access as a means of giving you the information you need, as soon as it's available. As we go through the process of developing a course, 99% of it can be ready but we can't publish until that last 1% falls in to place. Early Access helps to unlock the potential of our content early, to help you start your learning when you need it most. You not only get access to every chapter as it's delivered, edited, and updated, but you'll also get the finalized, DRM-free product to download in any format you want when it's published. As a member of Packt, you'll also be eligible for our exclusive offers, including a free course every day, and discounts on new and popular titles.
