A Unified Framework for Fair Spectral Clustering With Effective Graph Learning

Posted by dbos Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Qiao Wang, , , | Summary: We consider the problem of spectral clustering under group fairness constraints, where samples from each sensitive group are approximately proportionally represented in each cluster. Traditional fair spectral clustering (FSC) methods consist of two consecutive stages, i.e., performing fair spectral […]

Nuclear Structure Effects on Hyperfine Splittings in Ordinary and Muonic Deuterium

Posted by dbos Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Chen Ji, Xiang Zhang, Lucas Platter, , | Summary: Precision spectroscopy of hyperfine splitting (HFS) is a crucial tool for investigating the structure of nuclei and testing quantum electrodynamics (QED). However, accurate theoretical predictions are hindered by two-photon exchange (TPE) effects. We propose a novel formalism that […]
