Projects history
Radio astronomical calibration and imaging techniques
New, larger and more complex radio telescopes bring new challenges. Foremost among these is the calibration of the data in order to remove atmospheric and instrumental effects which corrupt the exceedingly faint signals from cosmic sources.
Blind source separation, subspace estimation, and factor analysis
Factor Analysis and extensionsMatlab code for very efficient computation of the FA decomposition: R = A A' + D (low rank plus diagonal).Software, Jul 2017 |
