Fig. 5From: KAMPNet: multi-source medical knowledge augmented medication prediction network with multi-level graph contrastive learningMulti-level unsupervised contrastive learning framework. It consists of three different contrastive learning processes: (1) Contrastive learning on medication code ontology graph; (2) Contrastive learning on diagnosis code ontology graph; (3) Contrastive learning on medical codes relation graphBack to article page
