Fig. 2From: Multi-type feature fusion based on graph neural network for drug-drug interaction predictionOverview of MGFEM. The MGFEM module applies graph interaction network and graph wrap unit to extract local information and global information of the molecular graph. When extracting the local information, the module updates the edge feature before updating the node feature. When extracting the global information, the module utilizes a supernode to promote the global propagation of informationBack to article page
