In this letter, we take into account the effect of the first-order approximation error and present a closed-form bound on the convergence in terms of the number of iterations required for the distance between the iterate and the limit point to reach an arbitrarily small fraction of the initial distance.

Due to the partial availability of bag-level labels, we focus on the incomplete-label MIML setting for the proposed active learning approach.

To reduce labeling cost, instead of labeling every instance, a group of instances (bag) is labeled by a single bag label.

Contrary to the common assumption in MIML that each instance in a bag belongs to one of the known classes, in novelty detection, we focus on the scenario where bags may contain novel-class instances.
