Detailed Description

A class for KMeans clustering.

This class takes as input an optional vtkTable on port LEARN_PARAMETERS specifying initial set(s) of cluster values of the following form:

          K     | Col1            |  ...    | ColN
     -----------+-----------------+---------+---------------
          M     |clustCoord(1, 1) |  ...    | clustCoord(1, N)
          M     |clustCoord(2, 1) |  ...    | clustCoord(2, N)
          .     |       .         |   .     |        .
          .     |       .         |   .     |        .
          .     |       .         |   .     |        .
          M     |clustCoord(M, 1) |  ...    | clustCoord(M, N)
          L     |clustCoord(1, 1) |  ...    | clustCoord(1, N)
          L     |clustCoord(2, 1) |  ...    | clustCoord(2, N)
          .     |       .         |   .     |        .
          .     |       .         |   .     |        .
          .     |       .         |   .     |        .
          L     |clustCoord(L, 1) |  ...    | clustCoord(L, N)

Because the desired value of K is often not known in advance and the results of the algorithm are dependent on the initial cluster centers, we provide a mechanism for the user to test multiple runs or sets of cluster centers within a single call to the Learn phase. The first column of the table identifies the number of clusters K in the particular run (the entries in this column should be of type vtkIdType), while the remaining columns are a subset of the columns contained in the table on port INPUT_DATA. We require that all user specified clusters be of the same dimension N and consequently, that the LEARN_PARAMETERS table have N+1 columns. Due to this restriction, only one request can be processed for each call to the Learn phase and subsequent requests are silently ignored. Note that, if the first column of the LEARN_PARAMETERS table is not of type vtkIdType, then the table will be ignored and a single run will be performed using the first DefaultNumberOfClusters input data observations as initial cluster centers.

When the user does not supply an initial set of clusters, then the first DefaultNumberOfClusters input data observations are used as initial cluster centers and a single run is performed.

This class provides the following functionalities, depending on the operation in which it is executed:

The code can handle a wide variety of data types as it operates on vtkAbstractArrays and is not limited to vtkDataArrays. A default distance functor that computes the sum of the squares of the Euclidean distance between two objects is provided (vtkKMeansDistanceFunctor). The default distance functor can be overridden to use alternative distance metrics.
