Large language models (LLMs) can generate credible but inaccurate responses, so researchers have developed uncertainty quantification methods to check the reliability of predictions. One popular ...

Each March 14 (3/14) mathematicians and science enthusiasts celebrate Pi Day, honoring the mathematical constant π (pi).

Most of you have used a navigation app like Google Maps for your travels at some point. These apps rely on algorithms that ...

Abstract: In this paper, a hypervolume contribution approximation method is proposed. The main idea is to find out all angular points in the hypervolume contribution region of the solution by ...

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 ...

If you’re already an iOS user and have just bought a shiny new iPhone or inherited an older model, you should know how to transfer data from iPhone to iPhone. It will help you transfer photos, apps, ...

Abstract: Reinforcement Learning is a branch of machine learning to learn control strategies that achieve a given objective through trial-and-error in the environment ...

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 ...
