A representation is identifiable if both the latent model and the transformation from latent to observed variables are unique.

In this review, we discuss approaches for learning causal structure from data, also called causal discovery.

In particular, we show that our strategies may require exponentially fewer interventions than the previously considered approaches, which optimize for structure learning in the underlying causal graph.

Most existing works focus on \textit{worst-case} or \textit{average-case} lower bounds for the number of interventions required to orient a DAG.

We compare our method with $w = 1$ to algorithms for finding sparse elimination orderings of undirected graphs, and show that taking advantage of DAG-specific problem structure leads to a significant improvement in the discovered permutation.

We consider the task of learning a causal graph in the presence of latent confounders given i. i. d.~samples from the model.

For constant density, we show that the expected $\log$ observational MEC size asymptotically (in the number of vertices) approaches a constant.

Determining the causal structure of a set of variables is critical for both scientific inquiry and decision-making.

We consider the problem of estimating the differences between two causal directed acyclic graph (DAG) models given i. i. d.~samples from each model.
