9. Causal Interventions to Reduce the Risk of Adverse Events in Stent Procedures

Statistics

Talk

The main medical intervention for coronary artery disease is stent implantation. In this context, we statistically estimate causal effects of alternate treatment regimes with the aim to lower the risk of adverse events as e.g. heart attacks. For this, a causal DAG is designed by domain experts and refined by a causal discovery algorithm. The estimated graph allows for appropriate confounder...

25. Extrema of high dimensional data

Statistics

Talk

In this talk we present a method to determine the directions of multivariate extremes. Therefore the concept of sparse regular variation of Meyer and Wintenberger (2021b) is introduced. In contrast to regular variation the limit measure in the definition of sparse regular variation is more sparse. The limit measure is called spectral measure and models the dependence in extremes. Sparse...

38. Signal Processing with Gabor Frames: Variational Problems, Compression, and Noise Removal

04/08/2022, 14:30

Statistics

Talk

We present solutions for variational problems, compression and noise removal using gabor frames. For an appropriate window function, a signal $ f \in \mathcal{L}^2(\mathbb{R}^d)$ possesses a non-orthogonal gabor frames expansions in terms of the dual frames with unconditional convergence in $ \mathcal{L}^2(\mathcal(R)^d) $. We derive approximate minimizers of variational problems and...
