Clustering large probabilistic graphs
WebFeb 1, 2016 · This paper proposes a novel method based on ensemble clustering for large probabilistic graphs that relies on co-occurrences of node pairs based on the probability of the corresponding common cluster graphs, and presents a Probabilistic co-association matrix as a consensus function to integrate base clustering results. WebOct 1, 2015 · Clustering of graphs can be categorized based on the type of a particular graph. This section lists the recent work on clustering noisy graphs, deterministic graphs, probabilistic graphs, and graph clustering using EAs. In case of probabilistic graphs there is only a marginal contribution to the problem of clustering.

WebJun 24, 2024 · Correlation clustering problem is a clustering problem which has many applications such as protein interaction networks, cross-lingual link detection, communication networks, and social computing. In this paper, we introduce two variants of correlation clustering problem: correlation clustering problem on uncertain graphs … WebIn this paper we provide an analogous tool for uncertain graphs, i.e., graphs whose edges are assigned a probability of existence. The fact that core decomposition can be computed efficiently in deterministic graphs does not guarantee efficiency in uncertain graphs, where even the simplest graph operations may become computationally intensive.

Thus, in this problem we wish to minimize the sum of squared distances to the nearest “clustercenter ... Webconnected, while those belonging to different clusters are far apart in a probabilistic sense [3]. An existing solution for structural clustering in uncertain graphs, referred to as USCAN [3], relies primarily on the key notion of reliable structural similarity, which quantifies the probability of the event that two vertices are structurally

This section lists the recent work on clustering noisy graphs, deterministic … WebClustering of large graphs can be categorized into two ways, topological and attributed clustering. Clusters based on connectivity criteria is topological clustering and by considering node or edge properties/attributes is known as attributed.
