Fig. 2From: HMCDA: a novel method based on the heterogeneous graph neural network and metapath for circRNA-disease associations predictionFlowchart of learning the embedding for target node. A Different types of entities were transformed into the same latent factor space by node content transformation. B All information in the same metapath with a same target entity is aggregated into target entity. C Information in different metapaths is aggregated into target entityBack to article page
