Method Details

[hide private]

NameModel(self, *args, **kwargs)

source code

Set the names of each node in the tree from a list of variable names.

**Arguments**

  - varNames: a list of names to be assigned

**Notes**

   1) this works its magic by recursively traversing all children

   2) The assumption is made here that the varNames list can be indexed
      by the labels of tree nodes

Overrides: Tree.TreeNode.NameTree: (inherited documentation)

ClassifyExample(self, example, appendExamples=0)

source code

Recursively classify an example by running it through the tree

**Arguments**

  - example: the example to be classified, a sequence at least
    2 long:
     ( id, sig )
    where sig is a BitVector (or something supporting __getitem__)
    additional fields will be ignored.

  - appendExamples: if this is nonzero then this node (and all children)
    will store the example

**Returns**

  the classification of _example_

Overrides: DecTree.DecTreeNode.ClassifyExample

init(self, *args, **kwargs)
(Constructor)

source code

constructor

**Arguments**

  - parent: the parent of this node in the tree

  - name: the name of the node

  - label: the node's label (should be an integer)

  - data: an optional data field

  - level: an integer indicating the level of this node in the hierarchy
    (used for printing)

  - isTerminal: flags a node as being terminal.  This is useful for those
    times when it's useful to know such things.

Overrides: Tree.TreeNode.__init__: (inherited documentation)
