Github Paveethranswam Drug Synergy Prediction Using Graph Neural Networks Decagon takes as input a multimodal graph of molecular and patient data and trains a graph convolutional neural network. the neural model can then be used to analyze, characterize, and predict polypharmacy side effects. Our model extends graph convolutional networks by incorporating support for multiple edge types, each type representing a different side effect, and by providing a form of efficient weight sharing for multimodal graphs with a large number of edge types.
Pdf Modeling Polypharmacy With Graph Convolutional Networks Dokumen To this aim, we develop a non linear, multi layer convolutional graph neural network model decagon that operates directly on graph g. decagon has two main components:. Why polypharmacy? many patients take multiple drugs to treat complex or co existing diseases: 25% of people ages 65 69 take more than 5 drugs 46% of people ages 70 79 take more than 5 drugs many patients take more than 20 drugs to treat heart disease, depression, insomnia, etc. Our approach develops a new graph convolutional neural network for multirelational link prediction in multimodal networks. Our model extends graph convolutional networks by incorporating support for multiple edge types, each type representing a different side effect, and by providing a form of efficient weight sharing for multimodal graphs with a large number of edge types.
Modeling Polypharmacy Side Effects With Graph Convolutional Networks Our approach develops a new graph convolutional neural network for multirelational link prediction in multimodal networks. Our model extends graph convolutional networks by incorporating support for multiple edge types, each type representing a different side effect, and by providing a form of efficient weight sharing for multimodal graphs with a large number of edge types. Such side effects are known as polypharmacy side effects, as they are associated with drug pairs (or higher order drug combinations) and cannot be attributed to either individual drug in the pair (in a drug combination). Decagon uses graph convolutions to embed the multimodal graph in a compact vector space and then uses the learned embeddings to predict side effects of drug combinations. Our model extends graph convolutional networks by incorporating support for multiple relation types, each type representing a different polypharmacy side effect, and by providing a form of efficient weight sharing for multimodal graphs with a large number of relation types.
