Overview of this book

Deep learning enables efficient and accurate learning from a massive amount of data. This book will help you overcome a number of challenges using various deep learning algorithms and architectures with R programming. This book starts with a brief overview of machine learning and deep learning and how to build your first neural network. You’ll understand the architecture of various deep learning algorithms and their applicable fields, learn how to build deep learning models, optimize hyperparameters, and evaluate model performance. Various deep learning applications in image processing, natural language processing (NLP), recommendation systems, and predictive analytics will also be covered. Later chapters will show you how to tackle recognition problems such as image recognition and signal detection, programmatically summarize documents, conduct topic modeling, and forecast stock market prices. Toward the end of the book, you will learn the common applications of GANs and how to build a face generation model using them. Finally, you’ll get to grips with using reinforcement learning and deep reinforcement learning to solve various real-world problems. By the end of this deep learning book, you will be able to build and deploy your own deep learning applications using appropriate frameworks and algorithms.

Exploring H2O

H2O has been around longer than Keras and MXNet and is still used widely. It makes use of Java and MapReduce in-memory compression to handle big datasets. H2O is used for many machine learning tasks and also supports deep learning. In particular, H2O provides native support for feedforward artificial neural networks (multilayer perceptrons). H2O performs automatic data preparation and missing value handling. Loading data requires the use of a special data type: H2OFrame.

Available functions

H2O only natively supports feedforward neural networks. Compared with the other main packages for deep learning, this creates an obvious limitation for this library. However, this is a very common deep learning implementation...
