Exploring Data with RapidMiner

By: Andrew Chisholm

Overview of this book

<p>Data is everywhere and the amount is increasing so much that the gap between what people can understand and what is available is widening relentlessly. There is a huge value in data, but much of this value lies untapped. 80% of data mining is about understanding data, exploring it, cleaning it, and structuring it so that it can be mined. RapidMiner is an environment for machine learning, data mining, text mining, predictive analytics, and business analytics. It is used for research, education, training, rapid prototyping, application development, and industrial applications.</p> <p>Exploring Data with RapidMiner is packed with practical examples to help practitioners get to grips with their own data. The chapters within this book are arranged within an overall framework and can additionally be consulted on an ad-hoc basis. It provides simple to intermediate examples showing modeling, visualization, and more using RapidMiner.<br /><br />Exploring Data with RapidMiner is a helpful guide that presents the important steps in a logical order. This book starts with importing data and then lead you through cleaning, handling missing values, visualizing, and extracting additional information, as well as understanding the time constraints that real data places on getting a result. The book uses<br />real examples to help you understand how to set up processes, quickly.</p> <p>This book will give you a solid understanding of the possibilities that RapidMiner gives for exploring data and you will be inspired to use it for your own work.</p>

RapidMiner Studio console printing


RapidMiner Studio provides the Print to Console operator. This is a very simple operator that outputs a value to the Log view (enabled from the GUI View menu). This value can be a macro or a string. As a process executes, its progress can be monitored by observing the Log view.

The following screenshot shows a small portion of a logfile corresponding to the output from two Print to Console operators. The first operator logs the value of a macro, whereas the second operator outputs the text directly:

The text Hello world in a macro is the content of a macro, whereas Hello world directly is the text entered into the Log to Console operator. The process to do this is called consoleLog.xml and is available with the files that accompany this book.
