And our analysis shows that on average 0.72% and 3.56% relative improvement of 2-hop DCA-(SL/RL) over 1-hop DCA-(SL/RL) or baseline-SL (without DCA) is statistically significant (with P-value < 0.005).
as Figure  (4.c) shows, when |E| increases, the running time of these two global EL models increases shapely, while our DCa model grows linearly.
