A system may use a configurable detected to identify a feature in a received image and an associated candidate tag based on user-defined items of interest, and to determine an associated accuracy metric. Moreover, based on the accuracy metric, costs of requesting the feedback from one or more individuals and a feedback threshold, the system may use a scheduler to selectively obtain feedback, having a feedback accuracy, about the candidate tag from the one or more individuals. Then, the system may generate a revised tag based on the feedback when the feedback indicates the candidate tag is incorrect. Next, the system presents a result with the feature and the candidate tag or the revised tag to another electronic device. Furthermore, based on a quality metric, the system may update labeled data that are to be used to retrain the configurable detector.
