The comparison of feature-selection classification performance achieved by distance-based and β atomic contacts and other methods in the literature.

r., sp., acc. and MCC represent recall, specificity, accuracy, and Matthew's correlation coefficient respectively. The bold numbers are the larger values in each of three pair-wise comparisons of βACV1 vs dACV1, βACV3 vs dACV3, and βACV1a vs dACV1a. In this table, significant features are selected on a dataset, and then a method with the selected features is evaluated on this dataset under a leave-one-out cross-validation process, as discussed in Materials and Methods.
