CCA-Zoo

cca-zoo is a collection of linear, kernel, and deep methods for canonical correlation analysis of multiview data. Where possible it follows the scikit-learn/mvlearn APIs and models therefore have fit/transform/fit_transform methods as standard.

Installation

Dependency of some implemented algorithms are heavy, such as pytorch and numpyro. We provide several options to accomodate the user's needs. For full details of algorithms included, please refer to section Implemented Methods

Standard installation:

pip install cca-zoo

For deep learning elements use:

pip install cca-zoo[deep]

For probabilistic elements use:

pip install cca-zoo[probabilistic]
