Overview of this book

This book explores an extensive range of machine learning techniques uncovering hidden tricks and tips for several types of data using practical and real-world examples. While machine learning can be highly theoretical, this book offers a refreshing hands-on approach without losing sight of the underlying principles. Inside, a full exploration of the various algorithms gives you high-quality guidance so you can begin to see just how effective machine learning is at tackling contemporary challenges of big data This is the only book you need to implement a whole suite of open source tools, frameworks, and languages in machine learning. We will cover the leading data science languages, Python and R, and the underrated but powerful Julia, as well as a range of other big data platforms including Spark, Hadoop, and Mahout. Practical Machine Learning is an essential resource for the modern data scientists who want to get to grips with its real-world application. With this book, you will not only learn the fundamentals of machine learning but dive deep into the complexities of real world data before moving on to using Hadoop and its wider ecosystem of tools to process and manage your structured and unstructured data. You will explore different machine learning techniques for both supervised and unsupervised learning; from decision trees to Naïve Bayes classifiers and linear and clustering methods, you will learn strategies for a truly advanced approach to the statistical analysis of data. The book also explores the cutting-edge advancements in machine learning, with worked examples and guidance on deep learning and reinforcement learning, providing you with practical demonstrations and samples that help take the theory–and mystery–out of even the most advanced machine learning methodologies.

Chapter 8. Clustering based learning

In this chapter, we will cover the clustering-based learning methods, and in specific the k-means clustering algorithm among others. Clustering-based learning is an unsupervised learning technique and thus works without a concrete definition of the target attribute. You will learn basics and the advanced concepts of this technique, and get hands-on implementation guidance in using Apache Mahout, R, Julia, Apache Spark, and Python to implement the k-means clustering algorithm.

The following figure depicts different learning models covered in this book, and the techniques highlighted in orange will be dealt in detail in this chapter:

The topics listed next are covered in depth in this chapter:

  • The core principles and objectives of the clustering-based learning methods

  • How to represent clusters and understand the required distance measurement techniques

  • Learning in depth, the k-means clustering and choosing the right clustering algorithm and the rules of cluster...
