Reward maximization for Pure Exploration: Minimax Optimal Good Arm Identification for Nonparametric Multi-Armed Bandits
arXiv
收藏 引用
arXiv 2024年
作者: Cho, Brian Meier, Dominik Gan, Kyra Kallus, Nathan Cornell Tech United States
In multi-armed bandits, the tasks of reward maximization and pure exploration are often at odds with each other. The former focuses on exploiting arms with the highest means, while the latter may require constant expl... 详细信息

Quantum distinguishability measures: projectors vs. states maximization
arXiv
收藏 引用
arXiv 2024年
作者: Budini, Adrián A. de Matos Filho, Ruynet L. Santos, Marcelo F. Centro Atómico Bariloche Avenida E. Bustillo Km 9.5 Bariloche8400 Argentina Fanny Newbery 111 Bariloche8400 Argentina Instituto de Física Universidade Federal do Rio de Janeiro Caixa Postal 68528 Rio de Janeiro21941-972 Brazil
The distinguishability between two quantum states can be defined in terms of their trace distance. The operational meaning of this definition involves a maximization over measurement projectors. Here we introduce an a... 详细信息

Factors in Fashion: Factor Analysis towards the Mode
arXiv
收藏 引用
arXiv 2024年
作者: Sun, Zhe Tu, Yundong Guanghua School of Management Peking University China
The modal factor model represents a new factor model for dimension reduction in high dimensional panel data. Unlike the approximate factor model that targets for the mean factors, it captures factors that influence th... 详细信息

arXiv 2020年
作者: Al-Sadoon, Majid M. Durham University Business School United Kingdom
This paper considers linear rational expectations models in the frequency domain. The paper characterizes existence and uniqueness of solutions to particular as well as generic systems. The set of all solutions to a g... 详细信息

arXiv 2024年
作者: Schmid, Luca Raviv, Tomer Shlezinger, Nir Schmalen, Laurent Hertzstr. 16 Karlsruhe76187 Germany School of ECE Ben-Gurion University of the Negev Be’er-Sheva Israel
We investigate the application of the factor graph framework for blind joint channel estimation and symbol detection on time-variant linear inter-symbol interference channels. In particular, we consider the expectatio... 详细信息

On the maximal correlation coefficient for the bivariate Marshall Olkin distribution
arXiv
收藏 引用
arXiv 2024年
作者: Bücher, Axel Staud, Torben Ruhr-Universität Bochum Fakultät für Mathematik Austria
We prove a formula for the maximal correlation coefficient of the bivariate Marshall Olkin distribution that was conjectured in Lin, Lai, and Govindaraju (2016, Stat. Methodol., 29:1–9). The formula is applied to obt... 详细信息

Quantifying predictive uncertainty of aphasia severity in stroke patients with sparse heteroscedastic Bayesian high-dimensional regression
arXiv
收藏 引用
arXiv 2023年
作者: Zgodic, Anja Bai, Ray Zhang, Jiajia Wang, Yuan Rorden, Chris McLain, Alexander C. Department of Epidemiology and Biostatistics University of South Carolina South Carolina United States Department of Statistics University of South Carolina South Carolina United States Department of Psychology University of South Carolina South Carolina United States
Sparse linear regression methods for high-dimensional data commonly assume that residuals have constant variance, which can be violated in practice. For example, Aphasia Quotient (AQ) is a critical measure of language... 详细信息
