Abstract
A computer-implemented method comprises training, using a validation set of input, a first classifier to predict when a second classifier will issue a classification error on a particular input, the first classifier generating a number of data buckets based on the validation set of input and populating a threshold lookup table for each data bucket based on a number of thresholds set for the second classifier during the training; storing each threshold lookup table in memory; obtaining a target error rate; obtaining a new input and running the new input through the first classifier, the first classifier selecting one of the data buckets for the new input; and selecting a threshold for the second classifier using the stored threshold lookup table for the selected data bucket and the target error rate.
