Hands-On Deep Learning with Apache Spark

By: Guglielmo Iozzia

Overview of this book

Deep learning is a subset of machine learning where datasets with several layers of complexity can be processed. Hands-On Deep Learning with Apache Spark addresses the sheer complexity of technical and analytical parts and the speed at which deep learning solutions can be implemented on Apache Spark. The book starts with the fundamentals of Apache Spark and deep learning. You will set up Spark for deep learning, learn principles of distributed modeling, and understand different types of neural nets. You will then implement deep learning models, such as convolutional neural networks (CNNs), recurrent neural networks (RNNs), and long short-term memory (LSTM) on Spark. As you progress through the book, you will gain hands-on experience of what it takes to understand the complex datasets you are dealing with. During the course of this book, you will use popular deep learning frameworks, such as TensorFlow, Deeplearning4j, and Keras to train your distributed models. By the end of this book, you'll have gained experience with the implementation of your models on a variety of use cases.

Importing Python models into the JVM with DL4J

In the previous chapter, we have learned how powerful and, at the same time, how easy the DL4J APIs are when it comes to configuring, building, and training multilayer neural network models. The possibilities to implement new models are almost innumerable relying on this framework only in Scala or Java.

But, let's have a look at the following search results from Google; they concern TensorFlow neural network models that are available on the web:

You can see that it is quite an impressive number in terms of results. And this is just a raw search. Refining the search to more specific model implementations means that the numbers are pretty high. But what's TensorFlow? TensorFlow (https://www.tensorflow.org/) is a powerful and comprehensive open...
