LazyIter: A Fast Algorithm for Counting Markov Equivalent DAGs and Designing Experiments

17 Jun 2020Ali AhmadiTeshniziSaber SalehkaleybarNegar Kiyavash

The causal relationships among a set of random variables are commonly represented by a Directed Acyclic Graph (DAG), where there is a directed edge from variable $X$ to variable $Y$ if $X$ is a direct cause of $Y$. From the purely observational data, the true causal graph can be identified up to a Markov Equivalence Class (MEC), which is a set of DAGs with the same conditional independencies between the variables...
