For RR models we have that CSTK+BA and CSTK+FA both achieve higher accuracy than ADD and FullAdd, with a statistical significante greater than 93.7%, as computed with the sign test.
we have that CSTK+BA has an average accuracy 7.94% higher than ADD and 5.89% higher than FullADD, while CSTK+FA improves on ADD and FullADD by 8.52% and 6.46%, respectively.
