Group invariance principles for causal generative models
The postulate of independence of cause and mechanism (ICM) has recently led
to several new causal discovery algorithms. The interpretation of independence
and the way it is utilized, however, varies across these methods. Our aim in
this paper is to propose a group theoretic framework for ICM to unify and
generalize these approaches. In our setting, the cause-mechanism relationship
is assessed by comparing it against a null hypothesis through the application
of random generic group transformations. We show that the group theoretic view
provides a very general tool to study the structure of data generating
mechanisms with direct applications to machine learning.Comment: 16 pages, 6 figure
