Minimum Average Cost Clustering

no code implementations NeurIPS 2010 Kiyohito Nagano, Yoshinobu Kawahara, Satoru Iwata

In this paper, we introduce the minimum average cost criterion, and show that the theory of intersecting submodular functions can be used for clustering with submodular objective functions.
