IDRLnet
IDRLnet is a machine learning library on top of Pytorch. 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.
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.
