Shrinkage for Covariance Estimation: Asymptotics, Confidence Intervals, Bounds and Applications in Sensor Monitoring and Finance
Ansgar Steland
When shrinking a covariance matrix towards (a multiple) of the identity matrix, the trace of the covariance matrix arises naturally as the optimal scaling factor for the identity t…
Automatic Processing and Solar Cell Detection in Photovoltaic Electroluminescence Images
Evgenii Sovetkin, Ansgar Steland
Electroluminescence (EL) imaging is a powerful and established technique for assessing the quality of photovoltaic (PV) modules, which consist of many electrically connected solar…
Segmentation of Photovoltaic Module Cells in Uncalibrated Electroluminescence Images
Sergiu Deitsch, Claudia Buerhop-Lutz, Evgenii Sovetkin +4
High resolution electroluminescence (EL) images captured in the infrared spectrum allow to visually and non-destructively inspect the quality of photovoltaic (PV) modules. Currentl…
On Convergence of Moments for Approximating Processes and Applications to Surrogate Models
Ansgar Steland
We study critera for a pair , of approximating processes which guarantee closeness of moments by generalizing known results for the special case that $…
