2003 journal article

Structured low rank approximation

LINEAR ALGEBRA AND ITS APPLICATIONS, 366(SPEC. ISS.), 157–172.

By: M. Chu n , R. Funderlic n & R. Plemmons*

Contributors: M. Chu n , R. Funderlic n & R. Plemmons*

author keywords: structured matrix; low rank approximation; optimization techniques; Toeplitz matrix
TL;DR: Two procedures for constructing the nearest structured low rank matrix are proposed and are flexible enough that they can be applied to any lower rank, any linear structure, and any matrix norm in the measurement of nearness. (via Semantic Scholar)

2002 journal article

The centroid decomposition: Relationships between discrete variational decompositions and SVDs

SIAM JOURNAL ON MATRIX ANALYSIS AND APPLICATIONS, 23(4), 1025–1044.

By: M. Chu*  & R. Fundelic

Contributors: M. Chu*  & R. Funderlic*

author keywords: data matrix; loading matrix; scoring matrix; indexing matrix; factor analysis; centroid method; singular value decomposition; low rank approximation; semidiscrete decomposition; centroid decomposition; low rank decompositions; integer programming
TL;DR: One major purpose of this work is to show fundamental relationships between the singular value, centroid, and semidiscrete decompositions, which unifies an entire class of truncated SVD approximations. (via Semantic Scholar)

1998 journal article

Rank modifications of semidefinite matrices associated with a secant update formula

SIAM JOURNAL ON MATRIX ANALYSIS AND APPLICATIONS, 20(2), 428–436.

By: M. Chu* , R. Funderlic* & G. Golub

Contributors: M. Chu* , R. Funderlic* & G. Golub

author keywords: rank-one reduction; Wedderburn theorem; BFGS update; DFP update; quasi-Newton methods; rank subtractivity; rank additivity
TL;DR: This paper analyzes rank modification of symmetric positive definite matrices H of the form H + P, where H −M denotes a step of reducing H to a lower-rank, symmetric and positive semidefinite matrix and (H −M) + P denotes astep of restoring H−M to a symmetricpositive definite matrix.
