Sparse principal component analysis and its -relaxation
Santanu S. Dey, Rahul Mazumder, Marco Molinaro +1
Principal component analysis (PCA) is one of the most widely used dimensionality reduction methods in scientific data analysis. In many applications, for additional interpretabilit…
The Trimmed Lasso: Sparsity and Robustness
Dimitris Bertsimas, Martin S. Copenhaver, Rahul Mazumder
Nonconvex penalty methods for sparse modeling in linear regression have been a topic of fervent interest in recent years. Herein, we study a family of nonconvex penalty functions t…
Subset Selection with Shrinkage: Sparse Linear Modeling when the SNR is low
Rahul Mazumder, Peter Radchenko, Antoine Dedieu
We study a seemingly unexpected and relatively less understood overfitting aspect of a fundamental tool in sparse linear modeling - best subset selection, which minimizes the resid…
