Integrated path stability selection

1 code implementation23 Mar 2024 Omar Melikechi, Jeffrey W. Miller

This yields a tighter bound on E(FP), resulting in a feature selection criterion that has higher sensitivity in practice and is better calibrated in terms of matching the target E(FP).

Sequential Gibbs Posteriors with Applications to Principal Component Analysis

no code implementations19 Oct 2023 Steven Winter, Omar Melikechi, David B. Dunson

Gibbs posteriors are proportional to a prior distribution multiplied by an exponentiated loss function, with a key tuning parameter weighting information in the loss relative to the prior and providing a control of posterior uncertainty.

Ellipsoid fitting with the Cayley transform

2 code implementations20 Apr 2023 Omar Melikechi, David B. Dunson

We introduce Cayley transform ellipsoid fitting (CTEF), an algorithm that uses the Cayley transform to fit ellipsoids to noisy data in any dimension.
