datafold is a Python package that provides data-driven models for point clouds to find an explicit mani-fold parametrization and to identify non-linear dynamical systems on these manifolds. Informally, a manifold is an usually unknown geometrical structure on which data is sampled. The explicit treatment of a manifold allows prior knowledge of a system and its problem-specific domain to be included. This can be the proximity between points in the dataset or functions defined on the phase space manifold of a dynamical system, such as (partially) known governing equation terms.
