Preface
Dear reader, welcome to an intuitive way of data analysis. Using a visual programming language based on dataflows, you can create an easy-to-understand analysis process, while it internally checks signals about some of the common problems. Obviously, any environment that does not help with proper documentation would be destined to fail, but KNIME's success is based not just on its high qualitycross-platformcode, but also on the good description about what it does and how you can use the building blocks.
This book covers the most common tasks that are required during the data preparation and visualization phase of data analysis using KNIME. Because of the size constraintsand to bring the best price/value for those who are already familiar with or not interested in modelingwe have not covered the modeling and machine learning algorithms available for KNIME. If you are already familiar with these algorithms, you will easily get familiar with the options in KNIME, and these are quite obvious to use, so you lose almost nothing. If you have not found time yet to get acquainted with these concepts, we encourage you to first learn for what these procedures are good and when you should use them. There are some good books, courses, and training availablethese are the ideal options for learningbut the Wikipedia articles can also give you a basic introduction specific to the algorithm you want to use.
What this book covers
, Installation and Using KNIME , introduces the user interface, the concepts used in the first three chapters, and how you can install and configure KNIME and its extensions.
, Data Preprocessing , covers the most common tasks, so that you can analyze your data, such as loading, transforming, and generating data; it also introduces the powerful regular expressions and some case studies.
, Data Exploration , describes how you can use KNIME to get an overview about your data, how you can visualize them in different forms, or even create publication quality figures.
, Reporting , introduces the KNIME reporting extension with the specific concepts, the user interface, and the basic blocks of reports.
What you need for this book
You only need a KNIME-compatible operating system, which is either a modern Linux, Mac OS X (10.6 or above), or Windows XP or above. The Java runtime is bundled with KNIME, and the first chapter describes how you can download and install KNIME. For this reason, you will need Internet connection too.
