In my limited understanding I understand LDA transforms data points in to a coordinate system where they can be easily discriminated/classified. SVD on the other hand is used for dimension reduction, can you help me bridge the gap by providing something to read on? > The approach in your reference (3) is highly amenable to parallel > implementation.
