Reviewing P2P network community detection
收藏 引用
IASTED European Conference on Internet and Multimedia Systems and Applications (EuroIMSA)
作者: Puig-Centelles, Anna Ripolles, Oscar Chover, Miguel Univ Jaume 1 Dept Lenguajes & Sistemas Informat Castellon de La Plana 12071 Spain
In this paper we present a summary of the state of the art concerning community detection in distributed computer architectures, for instance so-called P2P systems. The main algorithms for the extraction of communitie... 详细信息

Efficient community detection of network flows for varying Markov times and bipartite networks
收藏 引用
Physical Review E 2016年 第3期93卷 032309-032309页
作者: Masoumeh Kheirkhahzadeh Andrea Lancichinetti Martin Rosvall Department of IT and Computer Engineering Iran University of Science and Technology Teheran Iran Integrated Science Lab Department of Physics Umeå University SE-901 87 Umeå Sweden
community detection of network flows conventionally assumes one-step dynamics on the links. For sparse networks and interest in large-scale structures, longer timescales may be more appropriate. Oppositely, for large ... 详细信息

Physical Review E 2017年 第2期95卷 022302-022302页
作者: Michaël Fanuel Carlos M. Alaíz Johan A. K. Suykens Department of Electrical Engineering (ESAT) and STADIUS Center for Dynamical Systems Signal Processing and Data Analytics KU Leuven Kasteelpark Arenberg 10 B-3001 Leuven Belgium
Communities in directed networks have often been characterized as regions with a high density of links, or as sets of nodes with certain patterns of connection. Our approach for community detection combines the optimi... 详细信息

Physical Review E 2016年 第1期93卷 012303-012303页
作者: Pan Zhang Cristopher Moore M. E. J. Newman Santa Fe Institute Santa Fe New Mexico 87501 USA State Key Laboratory of Theoretical Physics Institute of Theoretical Physics Chinese Academy of Sciences Beijing 100190 China Physics Department and the Center for the Study of Complex Systems University of Michigan Ann Arbor Michigan 48109 USA
Recently, a phase transition has been discovered in the network community detection problem below which no algorithm can tell which nodes belong to which communities with success any better than a random guess. This r... 详细信息

Generative model for reciprocity and community detection in networks
收藏 引用
Physical Review Research 2021年 第2期3卷 023209-023209页
作者: Hadiseh Safdari Martina Contisciani Caterina De Bacco Max Planck Institute for Intelligent Systems Cyber Valley Tuebingen 72076 Germany
We present a probabilistic generative model and efficient algorithm to model reciprocity in directed networks. Unlike other methods that address this problem such as exponential random graphs, it assigns latent variab... 详细信息
