Apache Spark 2 for Beginners

By: Rajanarayanan Thottuvaikkatumana

Overview of this book

<p>Spark is one of the most widely-used large-scale data processing engines and runs extremely fast. It is a framework that has tools that are equally useful for application developers as well as data scientists.</p> <p>This book starts with the fundamentals of Spark 2 and covers the core data processing framework and API, installation, and application development setup. Then the Spark programming model is introduced through real-world examples followed by Spark SQL programming with DataFrames. An introduction to SparkR is covered next. Later, we cover the charting and plotting features of Python in conjunction with Spark data processing. After that, we take a look at Spark's stream processing, machine learning, and graph processing libraries. The last chapter combines all the skills you learned from the preceding chapters to develop a real-world Spark application.</p> <p>By the end of this book, you will have all the knowledge you need to develop efficient large-scale applications using Apache Spark.</p>

Preface

Chapter 7.  Spark Machine Learning

Calculations based on formulas or algorithms have been used commonly since ancient times to find the output for a given input. But without knowing the formulas or algorithms, computer scientists and mathematicians devised methods to generate formulas or algorithms based on an existing input/output dataset and predicted the output of a new input data based on the generated formulas or algorithms. Generally, this process of learning from a dataset and doing predictions based on the learning is known as machine learning. Machine learning originates from the study of artificial intelligence in computer science.

Practical machine learning has numerous applications that are being consumed by laymen on a daily basis. YouTube users now get suggestions for the next items to be played in the playlist based on the video they are currently viewing. Popular movie rating sites give ratings and recommendations based on the user preferences of movie genres. Social media...
