KNIME Essentials

Overview of this book

KNIME is an open source data analytics, reporting, and integration platform, which allows you to analyze a small or large amount of data without having to reach out to programming languages like R. "KNIME Essentials" teaches you all you need to know to start processing your first data sets using KNIME. It covers topics like installation, data processing, and data visualization including the KNIME reporting features. Data processing forms a fundamental part of KNIME, and KNIME Essentials ensures that you are fully comfortable with this aspect of KNIME before showing you how to visualize this data and generate reports. "KNIME Essentials" guides you through the process of the installation of KNIME through to the generation of reports based on data. The main parts between these two phases are the data processing and the visualization. The KNIME variants of data analysis concepts are introduced, and after the configuration and installation description comes the data processing which has many options to convert or extend it. Visualization makes it easier to get an overview for parts of the data, while reporting offers a way to summarize them in a nice way.

Chapter 3. Data Exploration

In this chapter, we will go through the main functions of KNIME visualization (except reporting) and other techniques to explore the data you have. This can be helpful when you want to do the preprocessing too, but you can also check the result of visualization or see how well they fit the computed models and the test/validation data. The topics covered in this chapter are as follows:

  • Statistics

  • Distance matrix

  • Visual properties

  • KNIME views and HiLiting

  • JFreeChart nodes

  • Some third party visualization options

  • Tips with HiLiting

  • Visualizing models
