New research highlights flaws in causal discovery methods

A new arXiv paper by Sairam Sundararaman details two fundamental flaws in the "guide, not bind" approach to defeasible priors in augmented Lagrangian causal discovery. The research demonstrates that sequential penalty ramping in Augmented Lagrangian methods can suppress correct causal edges before data can contradict them, and that standard correlation-matching objectives create an unresolvable tie between an edge and its reverse. The paper introduces the DADU relaxation rule, showing it violates conditions necessary to prevent this suppression, and mathematically proves the cost tie in correlation matching, suggesting covariance matching as an alternative.
