TL;DR: We propose four effective information-theoretic acquisition functions to be used for querying pairwise similarities between objects for active learning in the context of correlation clustering.

Abstract: We study correlation clustering where the pairwise similarities are not known in advance. For this purpose, we employ active learning to query pairwise similarities in a cost-efficient way. We propose a number of effective information-theoretic acquisition functions based on entropy and information gain. We extensively investigate the performance of our methods in different settings and demonstrate their superior performance compared to the alternatives.
