Fractional ridge regression: a fast, interpretable reparameterization of ridge regression [PDF]

open access: yesGigaScience, 2020
Abstract Background Ridge regression is a regularization technique that penalizes the L2-norm of the coefficients in linear regression. One of the challenges of using ridge regression is the need to set a hyperparameter (α) that controls the amount of regularization. Cross-validation is typically used

Droplets move over viscoelastic substrates by surfing a ridge [PDF]

open access: yesNature Communications, 2014
Liquid drops on soft solids generate strong deformations below the contact line, resulting from a balance of capillary and elastic forces. The movement of these drops may cause strong, potentially singular dissipation in the soft solid. Here we show that

Added mass: a complex face of tidal conversion [PDF]

open access: yesJournal of Fluid Mechanics 831, 101-127 (2017), 2018
This paper revisits the problem of tidal conversion at a ridge in a uniformly stratified fluid of limited depth using measurements of complex-valued added mass. When the height of a sub-marine ridge is non negligible with respect to the depth of the water, the tidal conversion can be enhanced in the supercritical regime or reduced in the subcritical ...

Energy and system dependence of high-$p_T$ triggered two-particle near-side correlations [PDF]

open access: yes, 2008
Previous studies have indicated that the near-side peak of high-$p_T$ triggered correlations can be decomposed into two parts, the \textit{Jet} and the \textit{Ridge}.

EEG Response to Sedation Interruption Complements Behavioral Assessment After Severe Brain Injury

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Accurate assessment of the level of consciousness and potential to recover in patients with severe brain injury underpins crucial decisions in the intensive care unit but remains a major challenge for the clinical team. The neurological wake‐up test is a widely used assessment tool. However, many patients' behavioral responses during

Curvature Tuning in Folded Strips Through Hyperstatic Applied Rotations

open access: yesFrontiers in Materials, 2019
Folding a strip of paper generates extremely localized plastic strains. The relaxation of the residual stresses results in a ridge that joins two flat faces at an angle known as the dihedral angle. When constrained isostatically, the strip will be at its

Filaments of crime: Informing policing via thresholded ridge estimation [PDF]

open access: yes, 2019
Objectives: We introduce a new method for reducing crime in hot spots and across cities through ridge estimation. In doing so, our goal is to explore the application of density ridges to hot spots and patrol optimization, and to contribute to the policing literature in police patrolling and crime reduction strategies.

Work and well-being over time: lone mothers and their children [PDF]

open access: yes, 2008
This report provides findings from the third wave of a qualitative longitudinal study, which began in 2003, following a sample of lone mothers who elected to move into employment supported by tax credits following a period of unemployment in receipt of ...

Ridge Estimation of Inverse Covariance Matrices from High-Dimensional Data

open access: yes, 2015
We study ridge estimation of the precision matrix in the high-dimensional setting where the number of variables is large relative to the sample size. We first review two archetypal ridge estimators and note that their utilized penalties do not coincide ...
