The Limitations of Optimization from Samples [PDF]

, 2016
In this paper we consider the following question: can we optimize objective functions from the training data we use to learn them? We formalize this question through a novel framework we call optimization from samples (OPS).

Development, characterization and modeling of mosquito repellent release from microporous devices

SPE Polymers, 2020
Nanocomposite strands with mosquito repellent DEET or Icaridin incorporated in a poly(ethylene‐co‐vinyl acetate) (EVA) matrix, with either pyrogenic silica or an organoclay as a nanofiller, were prepared by a twin‐screw extrusion compounding technique ...

Coded Caching based on Combinatorial Designs

, 2020
We consider the standard broadcast setup with a single server broadcasting information to a number of clients, each of which contains local storage (called \textit{cache}) of some size, which can store some parts of the available files at the server. The

Analyzing the Performance of Ideological and Political Education in Universities: A Neutrosophic Approach to Handling Truth, Indeterminacy, and Falsehood in Students' Responses [PDF]

Neutrosophic Sets and Systems
This paper presents a new way to evaluate ideological and political education (IPE) in universities using neutrosophic logic. Unlike traditional surveys that only show if students agree or disagree, this method looks deeper by also measuring how unsure ...

Perron Spectratopes and the Real Nonnegative Inverse Eigenvalue Problem

, 2015
Call an $n$-by-$n$ invertible matrix $S$ a \emph{Perron similarity} if there is a real non-scalar diagonal matrix $D$ such that $S D S^{-1}$ is entrywise nonnegative.

Scalable analytic eigenvalue extraction from a parahermitian matrix

Science Talks
In order to extract the analytic eigenvalues from a parahermitian matrix, the computational cost of the current state-of-the-art method grows factorially with the matrix dimension.

Recovery of eigenvectors from eigenvalues in systems of coupled harmonic oscillators

Physical Review Research, 2020
The eigenvector-eigenvalue identity relates the eigenvectors of a Hermitian matrix to its eigenvalues and the eigenvalues of its principal submatrices in which the jth row and column have been removed.
