Learning Sparse Representations by Non-Negative Matrix Factorization and Sequential Cone Programming
We exploit the biconvex nature of the Euclidean non-negative matrix factorization (NMF) optimization problem to derive optimization schemes based on sequential quadratic and secon...

Corrector-predictor methods for monotone linear complementarity problems in a wide neighborhood of the central path
Abstract. Two corrector-predictor interior point algorithms are proposed for solving monotone linear complementarity problems. The algorithms produce a sequence of iterates in the ...

A numerical recipe for accurate image reconstruction from discrete orthogonal moments
Recursive procedures used for sequential calculations of polynomial basis coefficients in discrete orthogonal moments produce unreliable results for high moment orders as a resul...

Link Adaptation in Linearly Precoded Closed-Loop MIMO-OFDM Systems with Linear Receivers
Abstract--Upcoming multi antenna systems such as 3GPPLTE employ code book based multi-mode precoding in order to adapt to a wide range of channel conditions. Link adaptation, which...
