On a Class of Matrix Completion Problems

Mathematische Nachrichten, 1989
The paper contains a unified treatment of special classes of matrix extension problems (``Schur analysis''). It is characterized as a combination of methods developed by V. P. Potapov and his collaborators in the study of the so-called fundamental matrix inequalities and of methods used by the last two authors.

The Euclidian Distance Matrix Completion Problem

SIAM Journal on Matrix Analysis and Applications, 1995
Motivated by the molecular mapping (or ``conformation'') problem, i.e., the problem of deducing the possible shapes of a molecule from partial (or inaccurate) information about interatomic distances, the authors study the completions of partial Euclidean distance matrices, i.e., the choice of values for each of the unspecified entries, resulting in a ...

The positive Q-matrix completion problem

Discrete Mathematics, Algorithms and Applications, 2015
A real [Formula: see text] matrix is a [Formula: see text]-matrix if for [Formula: see text] the sum of all [Formula: see text] principal minors is positive. A digraph [Formula: see text] is said to have positive [Formula: see text]-completion if every partial positive [Formula: see text]-matrix specifying [Formula: see text] can be completed to a ...

A Note on Matrix Completion Problems

Algebra Colloquium, 2012
Matrix completion problems are an important subclass of problems in matrix theory. An important question in matrix completion problems was posed by Oliveira in 1975, where the author proposed the description of the characteristic polynomial of a partitioned matrix of the form A = [Ai,j], i, j ∈ {1,2} (whose entries are in a field and A1,1, A2,2 are ...

Matrix completion problems in multidimensional systems

ISCAS'99. Proceedings of the 1999 IEEE International Symposium on Circuits and Systems VLSI (Cat. No.99CH36349), 2003
A ring with identity is Hermite if every unimodular row vector over the ring can be completed to form a unimodular square matrix over the ring. This paper constructs examples and counter-examples of Hermite rings and formulates several open problems, which have potential applications in multidimensional systems.

Euclidean distance matrix completion problems

Optimization Methods and Software, 2012
Our experiments show that the method easily solves the artificial problems introduced by More and Wu. It also solves the 12 much more difficult protein fragment problems introduced by Hendrickson, and the six larger protein problems introduced by Grooms, Lewis and Trosset.

State covariances and the matrix completion problem

52nd IEEE Conference on Decision and Control, 2013
State statistics of a linear system obey certain structural constraints that arise from the underlying dynamics and the directionality of input disturbances. Herein, we formulate completion problems of partially known state statistics with the added freedom of identifying disturbance dynamics.

Matrix Completion Problems

2000
In the matrix completion problem we are given a partial symmetric real matrix A with certain elements specified or fixed and the rest are unspecified or free; and, we are asked whether A can be completed to satisfy a given property (P) by assigning certain values to its free elements.

Randomized Robust matrix Completion for the Community Detection Problem

2018 52nd Asilomar Conference on Signals, Systems, and Computers, 2018
This paper focuses on the unsupervised clustering of large partially observed graphs. We propose a provable randomized framework in which a clustering algorithm is applied to a graph’s adjacency matrix generated from a stochastic block model. A sub-matrix is constructed using random sampling, and the low rank component is found using a convex ...
