Distributionally robust second-order stochastic dominance constrained optimization with Wasserstein ball

Posted by Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Yu Mei, Jia Liu, Zhiping Chen, , | Summary: We consider a distributionally robust second-order stochastic dominance constrained optimization problem. We require the dominance constraints hold with respect to all probability distributions in a Wasserstein ball centered at the empirical distribution. We adopt the sample approximation approach […]

FLTrust: Byzantine-robust Federated Learning via Trust Bootstrapping

Posted by Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Xiaoyu Cao, Minghong Fang, Jia Liu, Neil Zhenqiang Gong, | Summary: Byzantine-robust federated learning aims to enable a service provider to learn an accurate global model when a bounded number of clients are malicious. The key idea of existing Byzantine-robust federated learning methods is that the service […]

Interferometric Constraints on Spacelike Coherent Rotational Fluctuations

Posted by Chicago

Kavli Affiliate: Stephan S. Meyer | First 5 Authors: Jonathan W. Richardson, Ohkyung Kwon, H. Richard Gustafson, Craig Hogan, Brittany L. Kamai | Summary: Precision measurements are reported of the cross-spectrum of rotationally-induced differential position displacements in a pair of colocated 39 m long, high power Michelson interferometers. One arm of each interferometer is bent […]

Non-perturbative Effects on Electroweakly Interacting Massive Particles at Hadron Collider

Posted by Tokyo

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Taisuke Katayose, Shigeki Matsumoto, Satoshi Shirai, , | Summary: Electroweakly Interacting Massive Particles (EWIMPs), in other words, new massive particles that are charged under the electroweak interaction of the Standard Model (SM), are often predicted in various new physics models. EWIMPs are probed at hadron collider experiments […]

Virtual Distillation for Quantum Error Mitigation

Posted by Berkeley

Kavli Affiliate: K. Birgitta Whaley | First 5 Authors: William J. Huggins, Sam McArdle, Thomas E. O’Brien, Joonho Lee, Nicholas C. Rubin | Summary: Contemporary quantum computers have relatively high levels of noise, making it difficult to use them to perform useful calculations, even with a large number of qubits. Quantum error correction is expected […]
