WST and RWST analyses tools for astrophysical data.

PyWST : WST and RWST for astrophysics

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

The WST/RWST give you convenient sets of coefficients that describe your non-Gaussian data in a comprehensive way.

Install PyWST and check out our Jupyter notebook tutorial in the examples/ folder.

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

Note: For GPU-accelerated WST computations, take a look at kymatio (on which part of this code is based).
