WebOne approach is to learn more about the structure of the data. Dimensionality reduction supposes that the data are distributed near a low dimensional manifold. If this is the case, one might choose PCA if the manifold is (approximately) linear, and nonlinear dimensionality reduction (NLDR) if the manifold is nonlinear. http://techflare.blog/3-ways-to-do-dimensionality-reduction-techniques-in-scikit-learn/ christian f. jensen advokat
