Web13 apr. 2024 · To achieve efficient state representation learning, the dynamic hypergraph is constructed adaptively and the hypergraph convolution is applied. Despite the complexity of the relationship between agents in the environment, our method is able to extract effective features from large amounts of information to achieve efficient strategy learning. In mathematics, a hypergraph is a generalization of a graph in which an edge can join any number of vertices. In contrast, in an ordinary graph, an edge connects exactly two vertices. Formally, a directed hypergraph is a pair $${\displaystyle (X,E)}$$, where $${\displaystyle X}$$ is a set of … Meer weergeven Undirected hypergraphs are useful in modelling such things as satisfiability problems, databases, machine learning, and Steiner tree problems.
