High-Ordered Random Walks and Generalized Laplacians on Hypergraphs
نویسندگان
چکیده
Despite of the extreme success of the spectral graph theory, there are relatively few papers applying spectral analysis to hypergraphs. Chung first introduced Laplacians for regular hypergraphs and showed some useful applications. Other researchers treated hypergraphs as weighted graphs and then studied the Laplacians of the corresponding weighted graphs. In this paper, we aim to unify these very different versions of Laplacians for hypergraphs. We introduce a set of Laplacians for hypergraphs through studying high-ordered random walks on hypergraphs. We prove the eigenvalues of these Laplacians can effectively control the mixing rate of high-ordered random walks, the generalized distances/diameters, and the edge expansions.

Generalized Laplacian Eigenvalues of Random Hypergraphs
This is a sequel to an accepted talk of WAW 2011, where we introduced a set of generalized Laplacians of hypergraphs through the high-ordered random walks. In that paper, we proved the eigenvalues of these Laplacians can effectively control the mixing rate of highordered random walks, the generalized distances/diameters, and the edge expansions. In this talk, we will give a preliminary report o...
متن کاملRandom Walks in Hypergraph
Random walks on graphs have been extensively used for a variety of graph-based problems such as ranking vertices, predicting links, recommendations, and clustering. However, many complex problems mandate a high-order graph representation to accurately capture the relationship structure inherent in them. Hypergraphs are particularly useful for such models due to the density of information stored...
متن کاملRandom Walks on Hypergraphs with Applications to Disease-Gene Prioritization
Typically, gene interaction networks are expressed as graphs, storing pairwise interactions between genes. Because of the vast amount of literature on statistical graph inference, this is a useful representation in practice. However, such a pairwise representation ignores more complex features of gene interactions, such as gene regulation and assembly. In this thesis, we propose a hypergraph mo...
متن کاملOrdered Random Variables from Discontinuous Distributions
In the absolutely continuous case, order statistics, record values and several other models of ordered random variables can be viewed as special cases of generalized order statistics, which enables a unified treatment of their theory. This paper deals with discontinuous generalized order statistics, continuing on the recent work of Tran (2006). Specifically, we show that in general neither re...
متن کاملThe Cover Times of Random Walks on Hypergraphs
Random walks in graphs have been applied to various network exploration and networkmaintenance problems. In some applications, however, it may be more natural, and moreaccurate, to model the underlying network not as a graph but as a hypergraph, and solutionsbased on random walks require a notion of random walks in hypergraphs. While randomwalks in graphs have been extensive...
