Characteristic Neural Ordinary Differential Equations

Xingzi Xu, Ali Hasan, Khalil Elkhalil +2

We propose Characteristic-Neural Ordinary Differential Equations (C-NODEs), a framework for extending Neural Ordinary Differential Equations (NODEs) beyond ODEs. While NODEs model…

Generative Archimedean Copulas

Yuting Ng, Ali Hasan, Khalil Elkhalil +1

We propose a new generative modeling technique for learning multidimensional cumulative distribution functions (CDFs) in the form of copulas. Specifically, we consider certain clas…

Modeling Extremes with d-max-decreasing Neural Networks

Ali Hasan, Khalil Elkhalil, Yuting Ng +4

We propose a novel neural network architecture that enables non-parametric calibration and generation of multivariate extreme value distributions (MEVs). MEVs arise from Extreme Va…

Fisher Auto-Encoders

Khalil Elkhalil, Ali Hasan, Jie Ding +2

It has been conjectured that the Fisher divergence is more robust to model uncertainty than the conventional Kullback-Leibler (KL) divergence. This motivates the design of a new cl…

Improved Design of Quadratic Discriminant Analysis Classifier in Unbalanced Settings

Amine Bejaoui, Khalil Elkhalil, Abla Kammoun +2

The use of quadratic discriminant analysis (QDA) or its regularized version (R-QDA) for classification is often not recommended, due to its well-acknowledged high sensitivity to th…

Risk Convergence of Centered Kernel Ridge Regression with Large Dimensional Data

Khalil Elkhalil, Abla Kammoun, Xiangliang Zhang +2

This paper carries out a large dimensional analysis of a variation of kernel ridge regression that we call \emph{centered kernel ridge regression} (CKRR), also known in the literat…
