Rectangle counting in large bipartite graphs
WebbIt can process some of the largest publicly available bipartite datasets orders of magnitude faster than the state-of-the-art algorithms - achieving up to 1100× and 64× reduction in the number of thread synchronizations and traversed wedges, respectively. WebbCounting the number of perfect matchings in bipartite graphs amounts to computing the permanent of 0–1 matrices, which is # P -complete. It follows that there is a reduction from all the other counting problems you mention (which are all in # P) to this problem.

Webb27 juni 2014 · ABSTRACT. Rectangles are the smallest cycles (i.e., cycles of length 4) and most elementary sub-structures in a bipartite graph. Similar to triangle counting in uni-partite graphs, rectangle counting has many important applications where data is modeled as bipartite graphs.

Webb15 nov. 2024 · A graph can be defined as adjacency matrix NxN, where N is the number of nodes. This matrix can also be treated as a table of N objects in N-dimensional space. This representation allows us to use general-purpose dimension-reduction methods such as PCA, UMAP, tSNE, etc.
Webb15 dec. 2024 · A Bipartite Graph is a graph whose vertices can be divided into two independent sets, U and V such that every edge (u, v) either connects a vertex from U to V or a vertex from V to U. In other words, for every edge (u, v), either u belongs to U and v to V, or u belongs to V and v to U. stream the greatest beer run everstream the grinch online freeWebb1 juni 2014 · Bipartite Graph Rectangle Counting in Large Bipartite Graphs Authors: Jia Wang Ada W.
