Bandwidth Selection for Gaussian Kernel Ridge Regression via Jacobian Control [PDF]

arXiv, 2022
Most machine learning methods require tuning of hyper-parameters. For kernel ridge regression with the Gaussian kernel, the hyper-parameter is the bandwidth. The bandwidth specifies the length scale of the kernel and has to be carefully selected to obtain a model with good generalization.

Lexicographic maximin optimisation for fair bandwidth allocation in computer networks [PDF]

European Journal of Operational Research, 2008
This paper addresses the problem of bandwidth allocation in multi-application computer network environments. Allocations are determined from the solution of a multiple objective optimisation problem under network constraints, where the lexicographic maximin criterion is applied to solve the problem and guarantees fairness and efficiency properties to ...

Circularly Polarized Perovskite Photodetector with Photocurrent Dissymmetry Factors of up to 1.95 Enabled by Liquid Crystal

Advanced Functional Materials, EarlyView.
Photodetectors made using perovskite single crystals in combination with free‐standing cholesteric liquid crystal (CLC) polymer films exhibit photocurrent dissymmetry factors up to 1.95 for 520 nm circularly polarized light (CPL) excitation. The CPL spectral response of the photodetector is tunable over a broad range of wavelengths by tuning the ...
