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.

Streaming data with Apache Spark

In Chapter 1, The Apache Spark Ecosystem, the details about Spark Streaming and DStreams were covered. A new and different implementation of streaming, Structured Streaming, was introduced as an alpha release in Apache Spark 2.0.0. It finally became stable starting from Spark 2.2.0.

Structured Streaming (which has been built on top of the Spark SQL engine) is a fault-tolerant, scalable stream-processing engine. Streaming can be done in the same way batch computation is done, that is, on static data, which we presented in Chapter 1, The Apache Spark Ecosystem. It is the Spark SQL engine that's responsible for incrementally and continuously running the computation and for finally updating the results as data continues to stream. In this scenario, end-to-end, exactly-once, and fault-tolerance guarantees are ensured through Write Ahead Logs ...
