More Information
Summary:A method for active learning using privileged information is disclosed. A processing device receives a set of labeled examples and a set of unlabeled examples. For each unlabeled example in the set of unlabeled examples, the processing device determines whether to query at least one of an oracle to obtain a label for the unlabeled example or a teacher to obtain privileged information about the unlabeled example. The processing device outputs a decision rule based on minimizing a number of queries to the oracle for a label and the teacher for privileged information. Minimizing the number of queries to the teacher and the oracle is based on a cost of querying the teacher or the oracle.
