A new interpretation of the weighted pseudoinverse and its applications

Haibo Li

Consider the generalized linear least squares (GLS) problem $min ∥ Lx ∥_{2} s.t. ∥ M (A x - b) ∥_{2} = min$ . The weighted pseudoinverse $A_{M L}^{†}$ is the matrix that maps $b$ t…

Characterizing GSVD by singular value expansion of linear operators and its computation

Haibo Li

The generalized singular value decomposition (GSVD) of a matrix pair ${A, L}$ with $A \in R^{m \times n}$ and $L \in R^{p \times n}$ generalizes the singular value de…
