, i) both regression methods, (ii) only-insensitive regression, and (iii) only ridge regression. The best clusterization consisted of two groups only in (ii) and (iii)

, This led us to further inspect the two classes of candidate axioms only in terms of ridge regression. Specifically, we found 30 hard axioms with an overlap of around 40% with those found in the original paper
