fdeint 0.1.1

**FDEint** is a specialized Python package for solving Neural Fractional Differential Equations (NFDEs) with high efficiency and accuracy, specifically designed for PyTorch models. The neural network provided to the solver must be a subclass of `torch.nn.Module`. This package enables NFDEs to capture memory effects and long-range dependencies effectively.

  abstract = {Neural Ordinary Differential Equations (NODEs) are well-established architectures that fit an ODE, modeled by a neural network (NN), to data, effectively capturing complex dynamical systems. Recently, Neural Fractional Differential Equations (NFDEs) were proposed to incorporate non-integer order differential equations, capturing memory effects and long-range dependencies. In this work, we present an optimised implementation of the NFDE solver, achieving up to 570 times faster computations and up to 79 times higher accuracy. Our results demonstrate that for systems with fractional dynamics, NFDEs significantly outperform NODEs, particularly in extrapolation tasks on unseen time horizons. The code is available at https://github.com/zimmer-ing/Neural-FDE.}
