Gradient Descent PyTorch Geometric (PyG) is a geometric deep learning extension library for PyTorch. 04/2019: Our work on Compositional Imitation Learning is accepted at ICML 2019 as a long oral. de/ and their cleaned versions, the QM7 and QM9 dataset, and a handful of 3D mesh/point cloud datasets like FAUST, ModelNet10/40 and ShapeNet. As identification of miRNA-disease associations via biological experiments is time-consuming and expensive, computational methods are currently used as effective complements to determine the potential associations between disease and miRNA. pytorch geometric graph classification
