Bipartite Sparse Exchangeable Graphs for Machine Learning
bipartite graph is an ordered triple (VU; VI ; E) where VU; VI are sets of vertices and E VU VI is a set of edges u 2 VU means that there is a vertex with label u in the graph t 2 VI means that there is a vertex with label t in the graph (u; t) 2 E means that there is an edge between vertices u and t |
Does NetworkX have a bipartite graph class?
NetworkX does not have a custom bipartite graph class but the Graph () or DiGraph () classes can be used to represent bipartite graphs. However, you have to keep track of which set each node belongs to, and make sure that there is no edge between nodes of the same set.
What is a biadjacency matrix for a directed bipartite graph?
For directed bipartite graphs only successors are considered as neighbors. To obtain an adjacency matrix with ones (or weight values) for both predecessors and successors you have to generate two biadjacency matrices where the rows of one of them are the columns of the other, and then add one to the transpose of the other.
How to create a bipartite graph with node and EDGE data?
This function creates a bipartite graph that outputs an adjacency matrix with node and edge data. First, encode node data as a sparse matrix with one set of nodes as rows (beneficiary id) and another set of nodes as columns (physician id).
How do I check if a graph is bipartite?
The functions in the bipartite package do not check that the node set is actually correct nor that the input graph is actually bipartite. If B is connected, you can find the two node sets using a two-coloring algorithm: However, if the input graph is not connected, there are more than one possible colorations.
