# IDRLnet
|
|
|
|
IDRLnet is a machine learning library on top of [Pytorch](https://www.tensorflow.org/). Use IDRLnet if you need a machine
|
|
learning library that solves both forward and inverse partial differential equations (PDEs) via physics-informed neural
|
|
networks (PINN). IDRLnet is a flexible framework inspired by [Nvidia Simnet](https://developer.nvidia.com/simnet>).
|
|
|
|
## Features
|
|
|
|
IDRLnet supports
|
|
|
|
- complex domain geometries without mesh generation. Provided geometries include interval, triangle, rectangle, polygon,
|
|
circle, sphere... Other geometries can be constructed using three boolean operations: union, difference, and
|
|
intersection;
|
|
|
|
- sampling in the interior of the defined geometry or on the boundary with given conditions.
|
|
|
|
- enables the user code to be structured. Data sources, operations, constraints are all represented by ``Node``. The graph
|
|
will be automatically constructed via label symbols of each node. Getting rid of the explicit construction via
|
|
explicit expressions, users model problems more naturally.
|
|
|
|
- solving variational minimization problem;
|
|
|
|
- solving integral differential equation;
|
|
|
|
- adaptive resampling;
|
|
|
|
- recover unknown parameters of PDEs from noisy measurement data.
|
|
|
|
It is also easy to customize IDRLnet to meet new demands.
