Interface TreeModelDetail

All Superinterfaces:

ModelDetail

public interface TreeModelDetail

extends ModelDetail

TreeModelDetail holds details of a tree model. TreeModelDetail is a recursive partitioning of a multidimensional space that attempts to create partitions that are homogeneous with respect to a target. A single step of the partitioning is done via a predicate that splits a node into two or more children.
