Edit Clustering Build Node

To open the Edit Clustering dialog, either double-click a Clustering node, or right-click a Clustering node and select Edit.

Edit Clustering Build Node allows you to specify or change the characteristics of the models to build. Follow these steps:

  1. Select the Case ID for classification models. Case ID. Select one attribute from the Case ID list; this attribute must uniquely identify a case.


    Note:

    A Case ID is not required, however, a Case ID does help ensure build and test repeatability.

    If you specify a Case ID, all models in the node have the same Case ID.

  2. In the Models Settings list, select which models you want to build. For a Clustering node, you can build models using the k-Means Algorithm (KM) algorithm or the Orthogonal Partitioning Clustering (OC) algorithm.

    You can delete any of these models by selecting the model and clicking delete selected items

    To add a model, click add items

    See Delete Clustering Models or Add Model (Clustering) for more information.

  3. Auto is selected by default for all models. Auto controls automatic input selection for model build. Data miner decides which attributes to use for input. For example, attributes that are almost constant may not be suitable for input. If you deselect Auto, you can select attributes using Advanced Settings for Clustering Models.

  4. You can click OK to finish the node definition or you can click Advanced to specify data usage, algorithm settings, or performance settings; see Advanced Settings for Clustering Models for more information.
