CCA-Zoo

Unlock the hidden relationships in multiview data.

In today's data-driven world, revealing hidden relationships across multiview datasets is critical. CCA-Zoo is your go-to library, featuring a robust selection of linear, kernel, and deep canonical correlation analysis methods.

Designed to be user-friendly, CCA-Zoo is inspired by the ease of use in scikit-learn and mvlearn. It provides a seamless programming experience with familiar fit, transform, and fit_transform methods.

Whether you're a pip enthusiast or a poetry aficionado, installing CCA-Zoo is a breeze:

pip install cca-zoo
# For additional features
pip install cca-zoo[probabilistic, visualisation, deep]

For Poetry users:

poetry add cca-zoo
# For extra features
poetry add cca-zoo[probabilistic, visualisation, deep]

Note that deep requires torch and lightning which may be better installed separately following the PyTorch installation guide.

probabilistic requires numpyro which may be better installed separately following the NumPyro installation guide.

visualisation requires matplotlib and seaborn

CCA-Zoo is designed to be compatible with the machine learning ecosystem. It is built on top of scikit-learn, tensorly, torch, pytorch-lightning, and numpyro.

CCA-Zoo shines when it comes to high-dimensional data analysis. It significantly outperforms scikit-learn, particularly as dimensionality increases. For comprehensive benchmarks, see our script and the graph below.
