Both CAC and IGAC afford high accuracy on all three datasets (Table ). All accuracies are higher than 0.9 with the highest of 0.968 for IGAC on the BBB dataset. The biggest difference between CAC and IGAC can be found on the PGP dataset which is 0.942 for CAC and 0.961 for IGAC. The result of the Estrogen dataset is very close, 0.939 for CAC versus IGAC 0.943. Based on evaluations of these three datasets, IGAC performs relatively better than CAC.
