Generalized Canonical Correlation Analysis (GCCA) is a method which corresponds to solving an optimization problom objective to find the best linear shared space called G for the J view of a data
DeepGCCA is a non-linear version of GCCA which uses neural networks as the feature extractor functions instead of linear transformers. DGCCA is some how exention of DeepCCA for more than two views though it has a different objective function.
Pseudocode algorithm based on the paper,
