This repository is implementation of Generalized Canonical Correlation Analysis(GCCA). CCA can use only 2 data but GCCA can use more than 2 data.
CCA is the method to transform 2 data to one joint space. See example graph:
CCA inplementation contains PCCA (Probablistic Canonical Correlation Analysis) transformation that is assumed that there is latent space in 2 data.
GCCA is the method to transform multiple data to one joint space. See example graph:
You can give GCCA any number of data.
You can use 'git clone' command to install
You have to install python dependent libraries in advance as follow:
numpy==1.9.1
scipy==0.14.1
matplotlib==1.4.2
h5py==2.4.0
from cca import CCA
import logging
import numpy as np
# set log level
logging.root.setLevel(level=logging.INFO)
# create data in advance
a = np.random.rand(50, 50)
b = np.random.rand(50, 60)
# create instance of CCA
cca = CCA()
# calculate CCA
cca.fit(a, b)
# transform
cca.transform(a, b)
# transform by PCCA
cca.ptransform(a, b)
