Arrowhead completeness from minimal conditional independencies∗
نویسندگان
چکیده
We present two inference rules, based on so called minimal conditional independencies, that are sufficient to find all invariant arrowheads in a single causal DAG, even when selection bias may be present. It turns out that the set of seven graphical orientation rules that are usually employed to identify these arrowheads are, in fact, just different instances/manifestations of these two rules. Contains detailed proofs to main results.

Propositional Reasoning about Saturated Conditional Probabilistic Independence
Conditional independence provides an essential framework to deal with knowledge and uncertainty in Artificial Intelligence, and is fundamental in probability and multivariate statistics. Its associated implication problem is paramount for building Bayesian networks. Unfortunately, the problem does not enjoy a finite ground axiomatization and is already coNP-complete to decide for restricted sub...
متن کاملCausal Inference on Data Containing Deterministic Relations
Data containing deterministic relations cannot be handled by current constraint-based causal learning algorithms; they entail conditional independencies that cannot be represented by a faithful graph. Violation of the faithfulness property is characterized by an information equivalence of two sets of variables with respect to a reference variable. The conditional independencies do not provide i...
متن کاملCausal Models as Minimal Descriptions of Multivariate Systems
By applying the minimality principle for model selection, one should seek the model that describes the data by a code of minimal length. Learning is viewed as data compression that exploits the regularities or qualitative properties found in the data, in order to build a model containing the meaningful information. The theory of causal modeling can be interpreted by this approach. The regularit...

متن کاملDetermining full conditional independence by low order conditioning
A concentration graph associated with a random vector is an undirected graph where each vertex corresponds to one random variable in the vector. The absence of an edge between any pair of vertices (or variables) is equivalent to full conditional independence between these two variables given all the other variables. In the multivariate Gaussian case, the absence of an edge corresponds to a zero...
