A Minimal Causal Model Learner

The minimal-model semantics of causation is an essential concept for the identification of a best ffitting model in the sense of satisfactory consistent with the given data and be the simpler, less expressive model. Therefore to develop an algorithm being able to derive a minimal model is an interesting topic in the area of causal model discovery. various causal induction algorithms and tools developed so far can not guarantee that the derived model is a minimal model. This paper proves that the MML induction approach introduced by Wallace, et al is a minimal causal model learner. The experimental results obtained from the tests on a number of both artificial and real models provided in this paper conform this theoretical result.
