A Fused Latent and Graphical Model for Multivariate Binary Data
Yunxiao Chen, Xiaoou Li, Jingchen Liu +1
We consider modeling, inference, and computation for analyzing multivariate binary data. We propose a new model that consists of a low dimensional latent variable component and a s…
Chernoff Index for Cox Test of Separate Parametric Families
Xiaoou Li, Jingchen Liu, Zhiliang Ying
The asymptotic efficiency of a generalized likelihood ratio test proposed by Cox is studied under the large deviations framework for error probabilities developed by Chernoff. In p…
A Multilevel Approach towards Unbiased Sampling of Random Elliptic Partial Differential Equations
Xiaoou Li, Jingchen Liu
Partial differential equation is a powerful tool to characterize various physics systems. In practice, measurement errors are often present and probability models are employed to a…
Sequential Hypothesis Test with Online Usage-Constrained Sensor Selection
Shang Li, Xiaoou Li, Xiaodong Wang +1
This work investigates the sequential hypothesis testing problem with online sensor selection and sensor usage constraints. That is, in a sensor network, the fusion center sequenti…
