Within the Southern Ocean, sub-Antarctic regions are anticipated to face significant impacts related to climate change. The alteration of the circulation and properties of the water masses is expected to have widespread impacts on sub-Antarctic nearshore marine ecosystems. Satellite data provides…

Variable projection framework for the reduced-rank matrix approximation problem by weighted least-squares

Pascal Terray

In this monograph, we review and develop variable projection Gauss-Newton, Levenberg-Marquardt and Newton methods for the Weighted Low-Rank Approximation (WLRA) problem, which has now an increasing number of applications in many scientific fields. Particular attention is drawn at the robustness,…
