WebWe contruct hypergraph random walks utilizing optional “edge-dependent vertex weights”, which are weights associated with each vertex-hyperedge pair (i.e. cell weights on the incidence matrix). The probability transition matrix of this random walk is used to construct a normalized Laplacian matrix for the hypergraph. WebA matrix encoding the relation defining an incidence structure, typically in the finite case. An incidence system S = ( A, B, I) consists of two sets A and B with an incidence relation I between their elements, which is written as a I B for a ∈ A, B ∈ B. In this case one says that the element a is incident with B, or that B is incident with a.
