An efficient node ordering method using the conditional frequency for the K2 algorithm

Song Ko, Dae-Won Kim

Abstract: Highlights•A child has a better conditional frequency (or probability) under a correct parent than under an incorrect one.•The proposed method infers a correct causal relation by evaluating the conditional frequency through our scoring function.•Experimental results indicate that our proposed method outperforms previous methods in the accuracy and the consumed times.
