  1. This table shows the results of leave-one-out test for models built when the core cut-offs equal to 0.2 and 0.8 respectively. The first column is the composition of feature vectors. The second and the third columns are the CVA results of core cut-off = 0.2 and core cut-off = 0.8, respectively. The second line shows the CVA results of using all descriptors of both cut-offs. The values from the third line to the sixteenth line are the difference between the CVA of each leave-one-out test and the CVA using all descriptors.
