PyWST: WST and RWST for Astrophysics

PyWST is a public Python package designed for performing statistical analyses of two-dimensional data using the Wavelet Scattering Transform (WST) and the Reduced Wavelet Scattering Transform (RWST).

The WST/RWST provides a comprehensive set of coefficients that efficiently describe the non-Gaussian features of your data.

Install PyWST and explore our Jupyter notebook tutorial available in the examples/ folder.

If you use this package, please cite the following paper:

Note: For GPU-accelerated WST computations, consider using kymatio (which served as an initial inspiration for parts of this code).
