Weband privacy-preserving. However, traditional PCA is limited to learning linear structures of data and it is impossible to determine dimensionality reduction when the data pos-sesses nonlinear space structures. For nonlinear structure datasets, kernel principal component analysis (KPCA) is a very effective and popular technique to perform nonlinear WebDistributed PCA or an equivalent. We normally have fairly large datasets to model on, just to give you an idea: over 1M features (sparse, average population of features is around …
