# D-CCA: A Decomposition-based Canonical Correlation Analysis for High-dimensional Datasets

This python package implements the D-CCA method proposed in [1] for K=2 datasets. See [example.py](https://github.com/shu-hai/D-CCA/blob/master/example.py) for details, with Python 3.5 or above. For K>2 datasets, please use the [D-GCCA](https://github.com/shu-hai/D-GCCA) method.

D-CCA conducts the following decomposition:

 for 

where  and  share the same latent factors, but  and  have uncorrelated latent factors.

Note that  should be row-mean centered.
