Hashing with graphs
WebJan 1, 2011 · Hierarchical hashing on a data graph. x1, · · · , x8 are data points and y is a graph Laplacian eigenvector. The data points of filled circles take '1' hash bit and the others take '-1' hash bit. WebAbstract. Modeling multivariate time series (MTS) is critical in modern intelligent systems. The accurate forecast of MTS data is still challenging due to the complicated latent variable correlation. Recent works apply the Graph Neural Networks (GNNs) to the task, with the basic idea of representing the correlation as a static graph.
