KNIME Base Nodes version 4.3.2.v202103021015 by KNIME AG, Zurich, Switzerland
The fuzzy c-means algorithm is a well-known unsupervised learning
technique that can be used to reveal the underlying structure of the data.
Fuzzy clustering allows each data point to belong to several clusters, with
a degree of membership to each one.
Make sure that the input data is normalized to obtain better clustering results.
The list of attributes to use can be set in the second tab of the dialog.
The first output datatable provides the original datatable with the cluster memberships to each cluster. The second datatable provides the values of the cluster prototypes.
Additionally, it is possible to induce a noise cluster, to detect noise in the dataset, based on the approach from R. N. Dave: 'Characterization and detection of noise in clustering'.
