level_set_tree.LevelSetTree.prune¶

LevelSetTree.
prune
(threshold)¶ Prune the tree by recursively merging small leaf nodes into larger sibling nodes. The LevelSetTree is immutable, so pruning returns a new LevelSetTree whose nodes all contain more points than ‘threshold’.
Parameters: threshold : int
Nodes smaller than this will be merged.
Returns: out : LevelSetTree
A pruned level set tree. The original tree is unchanged.
Examples
>>> X = numpy.random.rand(100, 2) >>> tree = debacl.construct_tree(X, k=8, prune_threshold=2) >>> tree2 = tree.prune(threshold=12)
