WebPerforms linear Principal Component Analysis (PCA) on a low-rank matrix, batches of such matrices, or sparse matrix. This function returns a namedtuple (U, S, V) which is the nearly optimal approximation of a singular value decomposition of a centered matrix A A such that A = U diag (S) V^T A = U diag(S)V T. Note WebDistributed PCA PDMM for DCO A distributed PCA method can be obtained by simply approximating the global correlation matrix via the AC subroutine, Rˆ u,i = N ·AC({u iu T i} N =1;L) ≈ R u (31) In other words, each agent obtains an approximate of the global correlation matrix and the desired PCA can be then computed from Rˆ u,i.
