Is there a role for statistics in artificial intelligence?
Sarah Friedrich, Gerd Antes, Sigrid Behr +11
The research on and application of artificial intelligence (AI) has triggered a comprehensive scientific, economic, social and political discussion. Here we argue that statistics,…
Detecting Changes in the Second Moment Structure of High-Dimensional Sensor-Type Data in a -Sample Setting
Nils Mause, Ansgar Steland
The sample problem for high-dimensional vector time series is studied, especially focusing on sensor data streams, in order to analyze the second moment structure and detect ch…
Testing and Estimating Change-Points in the Covariance Matrix of a High-Dimensional Time Series
Ansgar Steland
This paper studies methods for testing and estimating change-points in the covariance structure of a high-dimensional linear time series. The assumed framework allows for a large c…
High-Confident Nonparametric Fixed-Width Uncertainty Intervals and Applications to Projected High-Dimensional Data and Common Mean Estimation
Yuan-Tsung Chang, Ansgar Steland
Nonparametric two-stage procedures to construct fixed-width confidence intervals are studied to quantify uncertainty. It is shown that the validity of the random central limit theo…
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…
