Optimal approximation of piecewise smooth functions using deep ReLU neural networks [PDF]
Neural Networks, 2017 We study the necessary and sufficient complexity of ReLU neural networks - in terms of depth and number of weights - which is required for approximating classifier functions in an Lp-sense.

Analytical Modeling of Magnetic Air-Gap Field Distribution Due to Armature Reaction
Energies, 2023 The following paper presents an analytical study of the air-gap magnetic field distribution produced by the armature reaction of a linear machine. Based on the method of images, the magnetic field generated by a current carrying conductor inside the air ...

Estimation of semiparametric models when the criterion function is not smooth [PDF]
Econometrica, 2003 We provide easy to verify sufficient conditions for the consistency and asymptotic normality of a class of semiparametric optimization estimators where the criterion function does not obey standard smoothness conditions and simultaneously depends on some preliminary nonparametric estimators.

Smoothing Parameter and Model Selection for General Smooth Models [PDF]
, 2015 This article discusses a general framework for smoothing parameter estimation for models with regular likelihoods constructed in terms of unknown smooth functions of covariates. Gaussian random effects and parametric terms may also be present.

IEEE Access, 2022 We present a method based on combining a smooth generalized pinball support vector machine (SVM) and variational autoencoders (VAEs) in chest X-ray (CXR) images.

Smooth Muscle-Targeted Overexpression of Peroxisome Proliferator Activated Receptor-γ Disrupts Vascular Wall Structure and Function. [PDF]
PLoS ONE, 2015 Activation of the nuclear hormone receptor, PPARγ, with pharmacological agonists promotes a contractile vascular smooth muscle cell phenotype and reduces oxidative stress and cell proliferation, particularly under pathological conditions including ...

Out-of-Sample Prediction in Multidimensional P-Spline Models
Mathematics, 2021 The prediction of out-of-sample values is an interesting problem in any regression model. In the context of penalized smoothing using a mixed-model reparameterization, a general framework has been proposed for predicting in additive models but without ...

Conditional Models for Non-smooth Ranking Loss Functions [PDF]
2009 Ninth IEEE International Conference on Data Mining, 2009 Learning to rank is an important area at the interface of machine learning, information retrieval and Web search. The central challenge in optimizing various measures of ranking loss is that the objectives tend to be non-convex and discontinuous. To make such functions amenable to gradient based optimization procedures one needs to design clever bounds.

Multi-Scale Zero-Order Optimization of Smooth Functions in an RKHS [PDF]
International Symposium on Information Theory, 2020 Consider the problem of optimizing a black-box function under the assumption that the function is Holder smooth and has bounded norm in the reproducing kernel Hilbert space associated with a given kernel. We propose the LP-GP-UCB algorithm which augments
