== Overview == *PyRSVD* provides an efficient [http://www.python.org/ python] implementation of a regularized singular value decomposition solver. The module is primarily aimed at applications in [http://en.wikipedia.org/wiki/Collaborative_filtering collaborative filtering], in particular the [ht...

In my geophysical work, I rely heavily upon a generalized inversion algorithm called Gauss-Newton optimization. The Gauss-Newton method minimizes objective functions that can be iteratively approximated by quadratics. This approach is particularly appropriate for least-squares inversions of m...

Analyzes accelerations caused by gravity, such as those recorded by GRACE. GAIA inverts these accelerations using a mascon technique to determine the mass distribution that matches the acceleration data. Currently, mass distributions can either be static in time, vary linearly, as well as osc...
