Web27 jun. 2024 · Let r ⩾ 2 be a fixed constant and let $ {\cal H} $ be an r-uniform, D-regular hypergraph on N vertices. Assume further that D → ∞ as N → ∞ and that degrees of pairs of vertices in $ {\cal H} $ are at most L where L = D/ ( log N) ω (1).We consider the random greedy algorithm for forming a matching in $ {\cal H} $.We choose a matching at … Web25 nov. 2024 · Graph and hypergraph matching are successful in tackling many real-world tasks that require 2D and 3D feature matching and alignment. Matching is a general problem in vision and graphs have always been quintessential for modeling information that has both local and longer range connections.
Webhypergraph matching, as well as the setting under multiple graphs. 3. Proposed Approaches We first present Neural Graph Matching (NGM), which can solve QAP for two-graph matching directly. The enhanced model NGM+ is then devised by adding edge embeddings. We show extension to hypergraph match-= (V 1 i Web23 jun. 2008 · Each feature set is modeled by a hypergraph where the complex relations are represented by hyper-edges. A match between the feature sets is then modeled as a hypergraph matching problem. We derive the hyper-graph matching problem in a probabilistic setting represented by a convex optimization.
Recall that a hypergraph H is a pair (V, E), where V is a set of vertices and E is a set of subsets of V called hyperedges. Each hyperedge may contain one or more vertices. A matching in H is a subset M of E, such that every two hyperedges e1 and e2 in M have an empty intersection (have no vertex in common). The … Meer weergeven In graph theory, a matching in a hypergraph is a set of hyperedges, in which every two hyperedges are disjoint. It is an extension of the notion of matching in a graph. Meer weergeven A graph without self-loops is just a 2-uniform hypergraph: each edge can be considered as a set of the two vertices that it connects. For example, this 2-uniform hypergraph … Meer weergeven A matching M is called perfect if every vertex v in V is contained in exactly one hyperedge of M. This is the natural extension of the notion of perfect matching in a graph. Meer weergeven The problem of finding a maximum-cardinality matching in a hypergraph, thus calculating $${\displaystyle \nu (H)}$$, is NP-hard even for 3-uniform hypergraphs (see Meer weergeven A hypergraph H = (V, E) is called intersecting if every two hyperedges in E have a vertex in common. A hypergraph H is intersecting if and only if it has no matching with two or more hyperedges, if and only if ν(H) = 1. Meer weergeven A fractional matching in a hypergraph is a function that assigns a fraction in [0,1] to each hyperedge, such that for every vertex v in V, the sum of fractions of hyperedges containing v is at most 1. A matching is a special case of a fractional matching in which all … Meer weergeven A set-family E over a ground set V is called balanced (with respect to V) if the hypergraph H = (V, E) admits a perfect fractional matching. For … Meer weergeven
