Title:
Geometry of the Faithfulness assumption in causal inference

Absract:

Algorithms for inferring causality are heavily based on the  
Faithfulness assumption. The unfaithful distributions have measure  
zero and can be seen as a collection of hypersurfaces in a hypercube.  
The Faithfulness condition alone is not sufficient to guarantee  
uniform consistency and Strong-Faithfulness has been proposed to  
overcome this problem. In contrast to the original Faithfulness  
assumption, the set of distributions satisfying Strong-Faithfulness  
does not have measure one. We study the (Strong) Faithfulness  
condition from the point of view of real algebraic geometry and give  
upper and lower bounds on the proportion of unfaithful distributions  
for various classes of graphs.
