A Systematic Investigation of Bias in Large Language Models for Advertising Relevance

Weiwei Wang, Yinchuan Xu, Jialu Gao +2

Large language models (LLMs) are increasingly used to judge how well an advertisement matches a query, but the fairness of these judgments has received limited attention. We conduc…

Nearest Neighbor Distances on a Circle: Multidimensional Case

Pavel M. Bleher, Youkow Homma, Lyndon L. Ji +2

We study the distances, called spacings, between pairs of neighboring energy levels for the quantum harmonic oscillator. Specifically, we consider all energy levels falling between…
