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,…
Consistency of Extreme Learning Machines and Regression under Non-Stationarity and Dependence for ML-Enhanced Moving Objects
Ansgar Steland
Supervised learning by extreme learning machines resp. neural networks with random weights is studied under a non-stationary spatial-temporal sampling design which especially addre…
Regularity of multifractional moving average processes with random Hurst exponent
Dennis Loboda, Fabian Mies, Ansgar Steland
A recently proposed alternative to multifractional Brownian motion (mBm) with random Hurst exponent is studied, which we refer to as Itô-mBm. It is shown that Itô-mBm is locally se…
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…
