Overview of this book

Machine learning aims to extract knowledge from data, relying on fundamental concepts in computer science, statistics, probability, and optimization. Learning about algorithms enables a wide range of applications, from everyday tasks such as product recommendations and spam filtering to cutting edge applications such as self-driving cars and personalized medicine. You will gain hands-on experience of applying these principles using Apache Spark, a resilient cluster computing system well suited for large-scale machine learning tasks. This book begins with a quick overview of setting up the necessary IDEs to facilitate the execution of code examples that will be covered in various chapters. It also highlights some key issues developers face while working with machine learning algorithms on the Spark platform. We progress by uncovering the various Spark APIs and the implementation of ML algorithms with developing classification systems, recommendation engines, text analytics, clustering, and learning systems. Toward the final chapters, we’ll focus on building high-end applications and explain various unsupervised methodologies and challenges to tackle when implementing with big data ML systems.

Preface

Introduction


Text analytics is at the of machine learning, mathematics, linguistics, and natural language processing. Text analytics, referred to as text mining in older literature, attempts to extract information and infer higher level concepts, sentiment, and semantic details from unstructured and semi-structured data. It is important to note that the traditional keyword searches are insufficient to deal with noisy, ambiguous, and irrelevant tokens and concepts that need to be filtered out based on the actual context.

Ultimately, what we are trying to do is for a given set of documents (text, tweets, web, and social media), is determine what the gist of the communication is and what concepts it is trying to convey (topics and concepts). These days, breaking down a document into its parts and taxonomy is too primitive to be considered text analytics. We can do better.

Spark provides a set of tools and facilities to make text analytics easier, but it is up to the users to combine the techniques...
