Integrated GNSS Attitude Determination and Positioning for Direct Geo-Referencing
Sensors, 2014 Direct geo-referencing is an efficient methodology for the fast acquisition of 3D spatial data. It requires the fusion of spatial data acquisition sensors with navigation sensors, such as Global Navigation Satellite System (GNSS) receivers.

Rational Optimization using Sum-of-Squares Techniques [PDF]
, 2007 Motivated by many control applications, this paper deals with the global solutions of unconstrained optimization problems. First, a simple SOS method is presented to find the infimum of a polynomial, which can be handled efficiently using the relevant ...

Sparsest factor analysis for clustering variables: a matrix decomposition approach [PDF]
, 2017 We propose a new procedure for sparse factor analysis (FA) such that each variable loads only one common factor. Thus, the loading matrix has a single nonzero element in each row and zeros elsewhere.

Local RBF approximation for scattered data fitting with bivariate splines [PDF]
, 2005 In this paper we continue our earlier research [4] aimed at developing effcient methods of local approximation suitable for the first stage of a spline based two-stage scattered data fitting algorithm.

Minimizing Rational Functions by Exact Jacobian SDP Relaxation Applicable to Finite Singularities [PDF]
, 2012 This paper considers the optimization problem of minimizing a rational function. We reformulate this problem as polynomial optimization by the technique of homogenization. These two problems are shown to be equivalent under some generic conditions.

Principal Component Analysis in an Asymmetric Norm [PDF]
, 2014 Principal component analysis (PCA) is a widely used dimension reduction tool in the analysis of many kind of high-dimensional data. It is used in signal processing, mechanical engineering, psychometrics, and other fields under different names.

Formal Proofs for Nonlinear Optimization [PDF]
, 2015 We present a formally verified global optimization framework. Given a semialgebraic or transcendental function $f$ and a compact semialgebraic domain $K$, we use the nonlinear maxplus template approximation algorithm to provide a certified lower bound of
