Chapter 11 Applications of SVD and Pseudo-inverses

WebWhile the SVD yields a "clean" way to construct the pseudoinverse, it is sometimes an "overkill" in terms of efficiency. The Moore-Penrose pseudoinverse can be seen as follows: Let ℓ: Rn → Rm be a linear map. Then ℓ induces an isomorphism ℓ ′: Ker(ℓ) ⊥ → Im(ℓ). Then the Moore-Penrose pseudoinverse ℓ +: Rm → Rn can be described as follows.
