continuiti

Learning function operators with neural networks.

continuiti is a Python package for deep learning on function operators with a focus on elegance and generality. It provides a unified interface for neural operators (such as DeepONet or FNO) to be used in a plug and play fashion. As operator learning is particularly useful in scientific machine learning, continuiti also includes physics-informed loss functions and a collection of relevant benchmarks.

Install the package using pip:

pip install continuiti

Or install the latest development version from the repository:

git clone https://github.com/aai-institute/continuiti.git
cd continuiti
pip install -e .[dev]

Our Documentation contains a collection of tutorials on how to learn operators using continuiti, a collection of how-to guides to solve specific problems, more background, and a class documentation.

In general, the operator syntax in continuiti is

v = operator(x, u(x), y)

mapping a function u (evaluated at x) to function v (evaluated in y).
