Going back to our example, we can model Facebook groups by the graph when is the set of all users, and any group in Facebook will be an edge (that notation stands for the Power Set of ) such that contains the users belongs to that … Webthe real world, hypergraphs have been used to solve prob-lems in many fields, such as social networks (Yang et al. 2024b), recommendation (Wang et al. 2024b) and natural language processing (Ding et al. 2024). To the best of our knowledge, we are the first to apply hypergraph neural net-works to information diffusion prediction task.

Web7 jan. 2024 · Just as ordinary hypergraphs are a generalization of graphs, directed hypergraphs are a natural generalization of digraphs. A directed hypergraph consists of a set of vertices V and a set of hyperarcs H, where a hyperarc is a pair < S, v >, S non empty subset of V and v ∈ V. S is also called the tail of the hyperarc, while v is the head. Web29 okt. 2014 · Pagerank is a commonly used graph analytic algorithm. It is used to find the relative importance of the vertices in a network. There are a wide range of applications where pagerank plays very important roles, for example in recommendation systems, link prediction, search engines, etc. We can think of the implication of pagerank in …

In this paper, we study r-uniform hypergraphs H without cycles of length less than five, employing the definition of a hypergraph cycle due to Berge. In particular, for r = 3, we show that if H has n vertices … WebHypergraphs. In the hypergraph, each hyperedge connects an arbitrary number of hypervertices instead of only two. So, the hypergraph model allows you to model group …
Web13 mrt. 2024 · Motivated by the above consideration, we follow the line of research in [18, 19, 31] to study nonlinear consensus processes over hypergraphs. Specifically, we investigate a discrete-time non-linear consensus process over temporal hypergraphs and the system is subject to random noises with general non-linear modulating functions.

For the first time in the literature, hypergraphs are used to capture the topology of trade agreements, while theusual graphs are used to represent trade fows.
