Hi, I’m Juan Diego Toscano. Thanks for stopping by.
This repository will help you to get involved in the physics-informed machine learning world. Inside the Tutorials folders, you will find several step-by-step guides on the basic concepts required to run and understand Physics-informed Machine Learning models (from approximating functions, solving and discovering ODE/PDEs with PINNs, to solving parametric PDEs with DeepONets).
Also, for advanced users, you can find our latest research in PINNs to achieve state-of-the-art performance using residual-based attention (RBA).
I reviewed some of these problems on my YouTube channel, so please watch them if you have time.
