Overview of this book

This book will teach you how to deploy large-scale dataset in deep neural networks with Hadoop for optimal performance. Starting with understanding what deep learning is, and what the various models associated with deep neural networks are, this book will then show you how to set up the Hadoop environment for deep learning. In this book, you will also learn how to overcome the challenges that you face while implementing distributed deep learning with large-scale unstructured datasets. The book will also show you how you can implement and parallelize the widely used deep learning models such as Deep Belief Networks, Convolutional Neural Networks, Recurrent Neural Networks, Restricted Boltzmann machines and autoencoder using the popular deep learning library Deeplearning4j. Get in-depth mathematical explanations and visual representations to help you understand the design and implementations of Recurrent Neural network and Denoising Autoencoders with Deeplearning4j. To give you a more practical perspective, the book will also teach you the implementation of large-scale video processing, image processing and natural language processing on Hadoop. By the end of this book, you will know how to deploy various deep neural networks in distributed systems using Hadoop.

This chapter discussed the most widely used applications of Machine learning and how they can be designed in the Hadoop framework. First, we started with a large video set and showed how the video can be decoded in the HDFS and later converted into a sequence file containing images for later processing. Large-scale image processing was discussed next in the chapter. The mapper used for this purpose has a shell script which performs all the tasks necessary. So, no reducer is necessary to perform this operation. Finally, we discussed how the natural language processing model can be deployed in Hadoop.
