Generating Filter and Select Nodes
In the tree builder window, or when browsing a decision tree model nugget, from the menus choose:
or
Filter Node. Generates a node that filters any fields not used by the current tree. This is a quick way to pare down the dataset to include only those fields that are selected as important by the algorithm. If there is a Type node upstream from this decision tree node, any fields with the role Target are passed on by the Filter model nugget.
Select Node. Generates a node that selects all records that fall into the current node. This option requires that one or more tree branches be selected on the Viewer tab.
The model nugget is placed on the stream canvas.
