Neural-trust-region algorithm for unconstrained optimization (Part 1)
Mostafa Rezapour, Thomas Asaki
In this paper (part 1), we describe a derivative-free trust-region method for solving unconstrained optimization problems. We will discuss a method when we relax the model order as…
A new sigmoidal fractional derivative for regularization
Mostafa Rezapour, Adebowale Sijuwade, Thomas J. Asaki
In this paper, we propose a new fractional derivative, which is based on a Caputo-type derivative with a smooth kernel. We show that the proposed fractional derivative reduces to t…
Nonasymptotic densities for shape reconstruction
Sharif Ibrahim, Kevin Sonnanburg, Thomas J. Asaki +1
In this work, we study the problem of reconstructing shapes from simple nonasymptotic densities measured only along shape boundaries. The particular density we study is also known…
Cone Monotonicity: Structure Theorem, Properties, and Comparisons to Other Notions of Monotonicity
Heather A. Van Dyke, Kevin R. Vixie, Thomas J. Asaki
In search of a meaningful 2-dimensional analog to mono- tonicity, we introduce two new definitions and give examples of and dis- cuss the relationship between these definitions and…
