High-Dimensional False Discovery Rate Control for Dependent Variables

no code implementations28 Jan 2024 Jasin Machkour, Michael Muma, Daniel P. Palomar

In recent years, multivariate false discovery rate (FDR) controlling methods have emerged, providing guarantees even in high-dimensional settings where the number of variables surpasses the number of samples.

FDR-Controlled Portfolio Optimization for Sparse Financial Index Tracking

no code implementations26 Jan 2024 Jasin Machkour, Daniel P. Palomar, Michael Muma

In high-dimensional data analysis, such as financial index tracking or biomedical applications, it is crucial to select the few relevant variables while maintaining control over the false discovery rate (FDR).

False Discovery Rate Control for Gaussian Graphical Models via Neighborhood Screening

no code implementations18 Jan 2024 Taulant Koka, Jasin Machkour, Michael Muma

Unfortunately, well-established estimators, such as the graphical lasso or neighborhood selection, are known to be susceptible to a high prevalence of false edge detections.

Sparse PCA with False Discovery Rate Controlled Variable Selection

no code implementations16 Jan 2024 Jasin Machkour, Arnaud Breloy, Michael Muma, Daniel P. Palomar, Frédéric Pascal

Sparse principal component analysis (PCA) aims at mapping large dimensional data to a linear subspace of lower dimension.
