scipy.cluster.hierarchy.ClusterNode¶
- class scipy.cluster.hierarchy.ClusterNode(id, left=None, right=None, dist=0, count=1)[source]¶
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.

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() Return a reference to the left child tree object. get_right() Returns a reference to the right child tree object. is_leaf() Returns True if the target node is a leaf. pre_order([func]) Performs pre-order traversal without recursive function calls.
