Average prediction accuracy on validation groups in cross-validation. Average of prediction accuracy was calculated on 5 validation groups in cross-validation. (A) Whole sets in 72-primer-31template sets were used for learning or validation. (B) The number of primer pair-template sets in 72-primer-31template was controlled to 1:1 by undersampling. Groups are Orange: PCR positive primer pair-template sets, Green: PCR negative primer pair-template sets, and Blue: all primer pair-template sets. Standard deviation within validation groups was shown as error bars.
