Schematic diagram of the Partial SVD application for extraction of PCs. White elements represent standard Partial SVD decomposition used in offline or “TEST” clustering. Grey elements show an online classification strategy in which the new SVD can be expressed as a product of old subspaces. These are small-matrix operations, and therefore rapid.
