  1. Comparing the predicted neutralization sensitivity of the SVM models using only the significant sites within gp120 as input, to the measured antibody response. We obtained sensitivity and specificity for detection of resistance to the particular antibody. Overall accuracy of the predictions in the whole dataset as well as within each subtype was determined. Standard-deviation of % accuracy across those subtypes is shown in the last column.
