WebThis example shows how to classify graphs that have multiple independent labels using graph attention networks (GATs). If the observations in your data have a graph structure with multiple independent labels, you can use a GAT [1] to predict labels for observations with unknown labels. Using the graph structure and available information on ... Webattention is able to learn the attention values between the nodes and their meta-path based neighbors, while the semantic-level attention aims to learn the attention values of different meta-paths for the spe-cific task in the heterogeneous graph. Based on the learned attention values in terms of the two levels, our model can get the optimal
