A Subspace Clustering Extension for the KNIME Data Mining Framework

Analyzing databases with many attributes per object is a recent challenge. For these high dimensional data it is known that traditional clustering algorithms fail to detect meaningful patterns. As a solution subspace clustering techniques were introduced. They analyze arbitrary subspace projections of the data to detect clustering structures. In this demonstration, we introduce the first subspace clustering extension for the well-established KNIME data mining framework. While KNIME offers a variety of data mining functionalities, subspace clustering is missing so far. Our novel extension provides a multitude of algorithms, data generators, evaluation measures, and visualization techniques specifically designed for subspace clustering. It deeply integrates into the KNIME framework allowing a flexible combination of the existing KNIME features with the novel subspace components. The extension is available on our website.
