scipy.cluster.hierarchy.ClusterNode

class scipy.cluster.hierarchy.ClusterNode(id, left=None, right=None, dist=0, count=1)

A tree node class for representing a cluster. Leaf nodes correspond to original observations, while non-leaf nodes correspond to non-singleton clusters.

The to_tree function converts a matrix returned by the linkage function into an easy-to-use tree representation.

• to_tree: for converting a linkage matrix Z into a tree object.

Methods

get_count()	The number of leaf nodes (original observations) belonging to the cluster node nd.
get_id()	The identifier of the target node.
get_left()	Returns a reference to the left child tree object.
get_right()	Returns a reference to the right child tree object.
is_leaf()	Returns True iff the target node is a leaf.
pre_order([func])	Performs preorder traversal without recursive function calls.
