关于多步社区发现的思考

Considerations about multistep community detection

Cristian Bisconti, Angelo Corallo, Laura Fortunato, Antonio A. Gentile

摘要:

网络中的社区发现问题及其意义在自然科学和社会科学中有着重要的应用,引起了人们极大的关注。已经开发了许多算法来解决这个问题,解决速度优化或计算分区的质量。在本文中,我们提出了一个多步骤的程序桥接最快,但不太准确的算法(粗聚类),与最慢,最有效的(细化)。通过采用节点的启发式排序,并将其中的一小部分分类为“关键”,可以将细化步骤限制在网络的这个子集上,从而节省计算时间。初步的数值结果进行了讨论,显示最终分区的改善。

英文摘要:

The problem and implications of community detection in networks have raised a huge attention, for its important applications in both natural and social sciences. A number of algorithms has been developed to solve this problem, addressing either speed optimization or the quality of the partitions calculated. In this paper we propose a multi-step procedure bridging the fastest, but less accurate algorithms (coarse clustering), with the slowest, most effective ones (refinement). By adopting heuristic ranking of the nodes, and classifying a fraction of them as `critical', a refinement step can be restricted to this subset of the network, thus saving computational time. Preliminary numerical results are discussed, showing improvement of the final partition.
