Graph-based methods coupled with specific distributional distances for adversarial attack detection
Dwight Nwaigwe, Lucrezia Carboni, Martial Mermillod +2
Artificial neural networks are prone to being fooled by carefully perturbed inputs which cause an egregious misclassification. These \textit{adversarial} attacks have been the focu…
Determinant of a Sum of Certain Kronecker Products
Dwight Nwaigwe
We compute the determinant of , where is square and where $\vec…
On the existence of the maximum likelihood estimate and convergence rate under gradient descent for multi-class logistic regression
Dwight Nwaigwe, Marek Rychlik
We revisit the problem of the existence of the maximum likelihood estimate for multi-class logistic regression. We show that one method of ensuring its existence is by assigning po…
Development of a New Image-to-text Conversion System for Pashto, Farsi and Traditional Chinese
Marek Rychlik, Dwight Nwaigwe, Yan Han +1
We report upon the results of a research and prototype building project \emph{Worldly~OCR} dedicated to developing new, more accurate image-to-text conversion software for several…
On the Convergence of WKB Approximations of the Damped Mathieu Equation
Dwight Nwaigwe
Consider the differential equation , . The form of the fundamental set of solutions are determined by Floquet theory. In the…
Overdamped dynamics of a Brownian particle levitated in a Paul trap
Gerard P. Conangla, Dwight Nwaigwe, Jan Wehr +1
We study the dynamics of the center of mass of a Brownian particle levitated in a Paul trap. We focus on the overdamped regime in the context of levitodynamics, comparing theory wi…
