Abstract:

Min-max disagreements are an important generalization of the correlation clustering problem (CorCP). It can be defined as follows. Given a marked complete graph G=(V, E), each edge in the graph is marked by a positive label '+' or a negative label '-' based on the similarity of the connected vertices. The goal is to find a clustering C of vertices V, so as to minimize the number of disagreements at the vertex with the most disagreements. Here, the disagreements are the positive cut edges and the negative non-cut edges produced by clustering C. This paper considers two robust min-max disagreements: min-max disagreements with outliers and min-max disagreements with penalties. Given parameter δ\in(0,1/14), we first provide a threshold-based iterative clustering algorithm based on LP-rounding technique, which is a (1/δ, 7/(1-14δ))-bi-criteria approximation algorithm for both the min-max disagreements with outliers and the min-max disagreements with outliers on one-sided complete bipartite graphs. Next, we verify that the above algorithm can achieve an approximation ratio of 21 for min-max disagreements with penalties when we set parameter δ=1/21. © 1996-2012 Tsinghua University Press.
