The Journal of Machine Learning Research 2022年 第1期23卷 4205-4232页
作者: Daniel Sanz-Alonso Ruiyi Yang Department of Statistics University of Chicago Chicago IL Committee on Computational and Applied Mathematics University of Chicago Chicago IL
In this paper we analyze the graph-based approach to semi-supervised learning under a manifold assumption. We adopt a Bayesian perspective and demonstrate that, for a suitable choice of prior constructed with sufficie... 详细信息

作者: Murugan, Jeff Pandit, Zayd Van Zyl, Hendrik J.R. The Laboratory for Quantum Gravity & Strings Department of Mathematics and Applied Mathematics University of Cape Town Cape Town South Africa The National Institute for Theoretical and Computational Sciences Private Bag X1 Matieland South Africa
We explore the relationship between complexity and duality in quantum systems, focusing on how local and non-local operators evolve under time evolution. We find that non-local operators, which are dual to local opera... 详细信息
