Fast, blind, and accurate: Tuning-free sparse regression with global linear convergence

CM Verdun, O Melnyk, F Krahmer… - The Thirty Seventh …, 2024 - proceedings.mlr.press
Many algorithms for high-dimensional regression problems require the calibration of
regularization hyperparameters. This, in turn, often requires the knowledge of the unknown …

Handling correlated and repeated measurements with the smoothed multivariate square-root Lasso

Q Bertrand, M Massias, A Gramfort… - Advances in Neural …, 2019 - proceedings.neurips.cc
A limitation of Lasso-type estimators is that the optimal regularization parameter depends on
the unknown noise level. Estimators such as the concomitant Lasso address this …

The EAS approach to variable selection for multivariate response data in high-dimensional settings

S Koner, JP Williams - Electronic Journal of Statistics, 2023 - projecteuclid.org
In this paper, we develop an epsilon admissible subsets (EAS) model selection approach for
performing group variable selection in the high-dimensional multivariate regression setting …

Significance testing for canonical correlation analysis in high dimensions

IW McKeague, X Zhang - Biometrika, 2022 - academic.oup.com
We consider the problem of testing for the presence of linear relationships between large
sets of random variables based on a postselection inference approach to canonical …

Learning graphs for dependence and conditional dependence at different levels

S Duan - 2024 - escholarship.org
Repeated measurements are common in many fields, where random variables are observed
repeatedly across different subjects. Such data have an underlying hierarchical structure …

Hyperparameter selection for high dimensional sparse learning: application to neuroimaging
