KNIME - The Konstanz Information Miner
KNIME is a graphical
compute workflow tool based on the Eclipse framework. It is available for
free as well as with commercial support. What you basically have is a
drawing board where you visually design your compute workflow (similar to WEKA).
You can drag and drop and connect different nodes. Nodes are representing
some functionality of your workflow. There are nodes for reading data from
databases or files, nodes for doing some calculations like data
clustering, and nodes for handling output or to visualize the results. The
enterprise edition has capabilities to exploit a compute cluster by
submitting jobs to Univa Grid Engine.
