There has been no title set for this workflow's metadata.

The workflow reads a data set to be clustered (Iris data). The workflow details how to use K-Means clustering with a number of different metrics: Inertia, Entropy, and Silhouette Coefficient. It also illustrates how to create an elbow graph.

Showing how you can loop through values of "k", calulating the distances to create an Elbow graph using KNIME Showing how you can use the same looping method as above to find optimal k. This one based on the Entropy metric. Showing another looping method you can use to find the optimal k. This one basedon Silhouette Coefficient.
