WebJan 15, 2024 · This adjoint approach is computationally very efficient because the gradients are analytically computed and the involved computational cost is independent on the number of parameters. However, the implementation of adjoint model requires an overwhelming programming effort, especially for the high-dimensional complex systems. WebJan 26, 2024 · Adjoint backpropagation (which is slower but more memory efficient) can be toggled with adjoint=True/False. The backend should be either "torchdiffeq" or "torchsde", corresponding to which underlying library to use for the solvers. If using torchsde then the stochastic term is zero -- so the CDE is still reduced to an ODE.
