Hybrid conjugate gradient-Occam algorithms for inversion of multifrequency and multitransmitter EM data

Egbert, Gary D. (Royal Astronomical Society, 2012-07)

We describe novel hybrid algorithms for inversion of electromagnetic geophysical data, combining the computational and storage efficiency of a conjugate gradient approach with an Occam scheme for regularization and step- ...
Robust principal component analysis of electromagnetic arrays with missing data

Smirnov, M. Yu; Egbert, G. D. (Royal Astronomical Society, 2012-09)

We describe a new algorithm for robust principal component analysis (PCA) of electromagnetic (EM) array data, extending previously developed multivariate methods to include arrays with large data gaps, and only partial o ...
