At ArangoDB we recently integrated community detection algorithms into our pregel based distributed bulk graph processing subsystem. We started with PageRank and betweenness centrality, and we are working on two community detection algorithms: Walktrap and Infomap. The result of the clustering will be represented as a dendrogram. Soft matter physics, general physics, the French research system, literature, philosophy. IWhen we do clustering on graphs we call it community detection IThe problem is more complex than clustering vector data because the distance between data points (vertices) is not measured by Euclidian distance but by how far away they are in graph distance IGraph distance d(a;b) length of the shortest path from vertex a to vertex b. 15 in ACM Computing Surveys. (2005, see references). Community Detection and Clique Percolation: This is a community detection problem. It’s sometimes referred to as community detection based on its commonality in social network analysis. Seasonality can be caused by factors, such as weather or holiday, and consists of periodic and repetitive patterns in a time series. A dendrogram is a tree and each level is a partition of the graph nodes. The community has built multiple add-ons leveraging the proposed standard. Name: python-igraph-debugsource.
