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

Downloading and understanding the famous Iris data for unsupervised classification


In this recipe, we and inspect the well-known Iris dataset in for the upcoming streaming KMeans recipe, which lets you see classification/clustering in real-time.

The data is housed on the UCI machine learning repository, which is a great source of data to prototype algorithms on. You will notice that R bloggers tend to love this dataset.

How to do it...

  1. You can start by downloading the dataset using either two of the following commands:
wget https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data

You can also use the following command:

curl https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data -o iris.data

You can also use the following command:

https://archive.ics.uci.edu/ml/machine-learning-databases/iris/iris.data
  1. Now we begin our first step of data exploration by examining how the data in iris.data is formatted:
head -5 iris.data
5.1,3.5,1.4,0.2,Iris-setosa
4.9,3.0,1.4,0.2...
