causaldag.classes.dag.DAG.shd¶
-
DAG.
shd
(other) → int[source]¶ Compute the structural Hamming distance between this DAG and the DAG
other
.Parameters: other – the DAG to which the SHD will be computed. Returns: The structural Hamming distance between and is the minimum number of arc additions, deletions, and reversals required to transform into (and vice versa). Return type: int Example
>>> import causaldag as cd >>> g1 = cd.DAG(arcs={(1, 2), (2, 3)}) >>> g2 = cd.DAG(arcs={(2, 1), (2, 3)}) >>> g1.shd(g2) 1
