Backward adaptive biorthogonalization
Laura Rebollo‐Neira · International Journal of Mathematics and Mathematical Sciences · 2004
A backward biorthogonalization approach is proposed, which modifies biorthogonal functions so as to generate orthogonal projections onto a reduced subspace. The technique is relevant to problems amenable to be represented by a general linear model. In particular, problems of data compression, noise reduction, and sparse representations may be tackled by the proposed approach.
