چکیده

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 is by positive label “+” or negative “−” based on similarity connected vertices. The goal to find xmlns:xlink="http://www.w3.org/1999/xlink">$\mathcal{C}$ vertices xmlns:xlink="http://www.w3.org/1999/xlink">$V$ so minimize number at vertex with most disagreements. Here, cut edges and non-cut produced . This paper considers two robust min-max disagreements: outliers penalties. parameter xmlns:xlink="http://www.w3.org/1999/xlink">$\delta\in(0,1/14)$ we first provide threshold-based iterative algorithm LP-rounding technique, which xmlns:xlink="http://www.w3.org/1999/xlink">$(1/\delta, 7/(1-14\delta))$ -bi-criteria approximation for both one-sided bipartite graphs. Next, verify that above achieve ratio 21 penalties when set xmlns:xlink="http://www.w3.org/1999/xlink">$\delta=1/21$

Correlation Clustering and Biclustering with Locally Bounded Errors

We consider a generalized version of the correlation clustering problem, defined as follows. Given a complete graph G whose edges are labeled with + or −, we wish to partition the graph into clusters while trying to avoid errors: + edges between clusters or − edges within clusters. Classically, one seeks to minimize the total number of such errors. We introduce a new framework that allows the o...

Correlation Clustering - Minimizing Disagreements on Arbitrary Weighted Graphs

We solve several open problems concerning the correlation clustering problem introduced by Bansal, Blum and Chawla [1]. We give an equivalence argument between these problems and the multicut problem. This implies an O(logn) approximation algorithm for minimizing disagreements on weighted and unweighted graphs. The equivalence also implies that these problems are APX-hard and suggests that impr...

Resource-Bounded Information Gathering for Correlation Clustering

We present a new class of problems, called resource-bounded information gathering for correlation clustering. Our goal is to perform correlation clustering under circumstances in which accuracy may be improved by augmenting the given graph with additional information. This information is obtained by querying an external source under resource constraints. The problem is to develop the most effec...

Robust, Complete, and Efficient Correlation Clustering

Correlation clustering aims at the detection of data points that appear as hyperplanes in the data space and, thus, exhibit common correlations between different subsets of features. Recently proposed methods for correlation clustering usually suffer from several severe drawbacks including poor robustness against noise or parameter settings, incomplete results (i.e. missed clusters), poor usabi...

A Robust Seedless Algorithm for Correlation Clustering

Finding correlation clusters in the arbitrary subspaces of highdimensional data is an important and a challenging research problem. The current state-of-the-art correlation clustering approaches are sensitive to the initial set of seeds chosen and do not yield the optimal result in the presence of noise. To avoid these problems, we propose RObust SEedless Correlation Clustering (ROSECC) algorit...
