A new paper co-authored by Yale SOM’s James Choi offers a simple tool to approximate an optimal investment strategy.

The numerical integration of stiff equations is a challenging problem that needs to be approached by specialized numerical methods. Exponential integrators form a popular class of such methods since ...

Abstract: Matrix approximation methods have successfully produced efficient, low-complexity approximate transforms for the discrete cosine transforms and the discrete Fourier transforms. For the DFT ...

Abstract: Nystrom approximation is one of the most popular approximation methods to accelerate kernel analysis on largescale data sets. Nystrom employs one single landmark set to ¨ obtain eigenvectors ...

Often comparisons of the theoretical and anatomical basis, data collection methods, reliability and success rates, as well as details of the sample population used to establish these guides cannot be ...

Method acting, the practice of experiencing a role as opposed to merely representing it, has been maligned and venerated in equal measure. Many famous and flashy performances exist by virtue of actors ...

This paper presents an analysis of properties of two hybrid discretisation methods for Gaussian derivatives, based on convolutions with either the normalised sampled Gaussian kernel or the integrated ...

ABSTRACT: Accurately approximating higher order derivatives is an inherently difficult problem. It is shown that a random variable shape parameter strategy can improve the accuracy of approximating ...

Quantum computers, utilizing versatile qubits, are at the forefront of solving complex optimization problems like the traveling salesman dilemma, traditionally plagued by computational inefficiency.

The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a Berlin team led by theoretical physicist Prof. Dr. Jens Eisert of Freie Universität Berlin ...
