VC-PCR: A Prediction Method based on Supervised Variable Selection and Clustering
Rebecca Marion, Johannes Lederer, Bernadette Govaerts +1
Sparse linear prediction methods suffer from decreased prediction accuracy when the predictor variables have cluster structure (e.g. there are highly correlated groups of variables…
DeepMoM: Robust Deep Learning With Median-of-Means
Shih-Ting Huang, Johannes Lederer
Data used in deep learning is notoriously problematic. For example, data are usually combined from diverse sources, rarely cleaned and vetted thoroughly, and sometimes corrupted on…
Thresholded Adaptive Validation: Tuning the Graphical Lasso for Graph Recovery
Mike Laszkiewicz, Asja Fischer, Johannes Lederer
Many Machine Learning algorithms are formulated as regularized optimization problems, but their performance hinges on a regularization parameter that needs to be calibrated to each…
