1. A method, comprising:
receiving a set of input signals;
determining, with a first classifier, a first classification of the set of input signals;
conditionally activating a second classifier based on the first classification; and
determining, using the second classifier, at least one second classification of the set of input signals, wherein the at least one second classification is a sub-category of the first classification.
