================= HiDRA ================= Hierarchical Network for Drug Response Prediction with Attention Model Architecture -------------------- HiDRA starts with a dense two-layer drug encoding network. The gene expression data is then split up into pathways based on KEGG data, and each pathway has its own dense encoding network with gene-level and pathway-level attention modules that incorporate the drug encodings. Finally, a dense two-layer network takes concatenated drug and pathway outputs and generates a response prediction. Feature Representation -------------------- * Cancer features: * Gene Expression: converted to z-scores for each cell line, genes not present in the KEGG pathway data are removed * Drug features: * Drug Fingerprints: 512-bit Morgan fingerprints generated from SMILES strings with rdkit URLs -------------------- - `Original GitHub `__ - `IMPROVE GitHub `__ References -------------------- `1. `_ I.
