Braking indices as probes of r-mode spin-down in young pulsars
Shahram Abbassi, Armin Memarian, Evelyn Sophia Guest +1
We present a timing-based framework for interpreting braking-index measurements in young pulsars using a four-channel spin-down model that includes particle-wind, magnetic-dipole,…
Restricted nonlinear shrinkage of high-dimensional residual covariance matrices in multivariate regressions
Hamid Karamikabir, Mohammad Arashi
We study estimation of the p*p residual scatter (shape) matrix in a high-dimensional multivariate linear regression, where p and n grow proportionally. When the coefficient matrix…
Mens: Nonlinear shrinkage estimation in nonparanormal models for financial applications
Hamid Karamikabir, Mohammad Arashi
We develop a theory of nonlinear shrinkage covariance estimation for nonparanormal (Gaussian-copula) models, in which each observed coordinate is an unknown strictly increasing tra…
Jeans criterion in hydrostatic stratified media
Mahmood Roshan, Asiyeh Habibi
The classical Jeans stability criterion neglects spatial gradients in background physical quantities such as density and pressure. Here, we revisit the Jeans analysis for a non-rot…
Quantum Adversarial Machine Learning: From Classical Adaptations to Quantum-Native Methods
Roozbeh Razavi-Far, Mohammad Meymani, Erfan Mahmoudinia +6
Machine learning has revolutionized numerous industrial domains. Despite recent advances, machine learning models remain vulnerable to adversarial threats. Adversarial machine lear…
A Dynamic-Growing Fuzzy-Neuro Controller, Application to a 3PSP Parallel Robot
Mohsen Jalaeian-Farimani, Mohammad-R Akbarzadeh-T, Alireza Akbarzadeh +1
To date, various paradigms of soft-Computing have been used to solve many modern problems. Among them, a self organizing combination of fuzzy systems and neural networks can make a…
