Dynamic heterogeneous graph

WebIn such settings, the graph becomes a dynamic heterogeneous graph. The graph is heterogeneous as there are two types of nodes and four types of edges. The graph is dynamic because the “senti-ment” edges between word and sentiment nodes are dynamically built and modified during the real-time prediction process rather than fixed. … WebHeterogeneous graphs come with different types of information attached to nodes and edges. Thus, a single node or edge feature tensor cannot hold all node or edge features of the whole graph, due to differences in type and dimensionality. Instead, a set of types need to be specified for nodes and edges, respectively, each having its own data ...
