Solver pytorch
WebPyTorch Implementation of Differentiable ODE Solvers. This library provides ordinary differential equation (ODE) solvers implemented in PyTorch. Backpropagation through … WebPyTorch [23] primitives. Beyond prototyping of implicit models, this allows in example direct hybridization of solvers and neural networks [24], [25], direct training of deep neural solvers [26], [27] or test–time ablations to determine the effect of numerical solver on task performance, all with minimal implementation overhead.
