1. A computer-implemented method for configuring a classifier structure, the method comprising: receiving a classifier structure for identifying a feature of input data, the structure having a parent binary classifier and a plurality of child binary classifiers; adding a plurality of operating points to the parent binary classifier, each operating point for controlling how data is classified by the parent binary classifier for distribution to the child binary classifiers, each operating point having a respective cost; and setting the operating points to minimize the total cost based on the resources available to the child binary classifiers.
