Interchannel EEG synchronization, as well as its violation, is an important diagnostic sign of a number of diseases. In particular, during an epileptic seizure, such synchronization occurs starting from some pairs of channels up to many pairs in a ...

AbstractLet X be an n by p matrix, and define RX(λ)=X(X′X+λPX′)-X′, which is called a ridge operator, where λ is a nonnegative constant (called the ridge parameter), and PX′=X′(XX′)-X. Various properties of RX(λ) were discussed, including additive decompositions of this matrix similar to those of PX≡RX(0)=X(X′X)-X′, the orthogonal projector onto the ...

Ridge Regression and Other Kernels for Genomic Selection with R Package rrBLUP
Many important traits in plant breeding are polygenic and therefore recalcitrant to traditional marker‐assisted selection. Genomic selection addresses this complexity by including all markers in the prediction model.

Effectiveness of vertical ridge augmentation interventions: A systematic review and meta-analysis.
AIM The primary aim of this systematic review was to evaluate the effect of various techniques used for vertical ridge augmentation on clinical vertical bone gain. MATERIAL AND METHODS A protocol was developed to answer the following focused question: "

Adding bias to reduce variance in psychological results: A tutorial on penalized regression [PDF]
Regression models are commonly used in psychological research. In most studies, regression coefficients are estimated via maximum likelihood (ML) estimation.

Comparison of Highbush Blueberry (Vaccinium corymbosum L.) under Ridge and Pot Production
Due to the specific requirements for low soil pH, new production methods are being introduced for highbush blueberry (Vaccinium corymbosum L.). Planting in pots has gained popularity in recent years due to the easier control of the substrate pH.

Bose enhancement and the ridge
We point out that Bose enhancement in a hadronic wave function generically leads to correlations between produced particles. We show explicitly, by calculating the projectile density matrix in the Color Glass Condensate approach to high-energy hadronic collisions, that the Bose enhancement of gluons in the projectile leads to azimuthal collimation of ...

The mean composition of ocean ridge basalts
The mean composition of mid‐ocean ridge basalts (MORB) is determined using a global data set of major elements, trace elements, and isotopes compiled from new and previously published data.

High-Dimensional Asymptotics of Prediction: Ridge Regression and Classification [PDF]
We provide a unified analysis of the predictive risk of ridge regression and regularized discriminant analysis in a dense random effects model. We work in a high-dimensional asymptotic regime where $p, n \to \infty$ and $p/n \to \gamma \in (0, \, \infty)$

Ridge Regression, Hubness, and Zero-Shot Learning [PDF]
This paper discusses the effect of hubness in zero-shot learning, when ridge regression is used to find a mapping between the example space to the label space.
