Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Group-Orthogonal Subsampling for Big Data Linear Mixed Models
大数据 线性混合模型 群正交 子采样
2023/5/10
Linear mixed model is a popular and common modeling method in statistical analysis. It is computationally difficult to obtain parameter estimates in linear mixed model for big data. The current subsam...

Multiscale Representations for Manifold-Valued Data
Symmetric Space Lie Group Two-Scale Refi nement Scheme
2015/8/21
We describe multiscale representations for data observed on equispaced grids and taking
values in manifolds such as: the sphere S2, the special orthogonal group SO(3), the positive
definite ma...

THE 1987 WALD MEMORIAL LECTURES A GENERALIZATION OF SPECTRAL ANALYSIS WITH APPLICATION TO RANKED DATA
Spectral analysis the simulation data the space
2015/7/14
An analog of the spectral analysis of time series is developed for data in
general spaces. This is applied to data from an election in which 5738 people
rank ordered five candidates. Group theoret...

Compound decision in the presence of proxies with an application to spatio-temporal data
Compound decision presence of proxies application
2011/1/19
We study the problem of incorporating covariates in a compound decision setup.It is desired to estimate the means of n response variables, which are independent and normally distributed, and each is a...
Algebras graded by discrete Doi-Hopf data and the Drinfeld double of a Hopf group-coalgebra
Algebras discrete Doi-Hopf data the Drinfeld double
2010/11/9
We study Doi-Hopf data and Doi-Hopf modules for Hopf group-coalgebras. We introduce modules graded by a discrete Doi-Hopf datum; to a Doi-Hopf datum over a Hopf group coalgebra, we associate an algebr...
Is Brownian motion necessary to model high-frequency data?
Brownian motion high-frequency data
2010/11/18
This paper considers the problem of testing for the presence of a continuous part in a semimartingale sampled at high frequency. We provide two tests, one where the null hypothesis is that a continuou...
Deciding the dimension of effective dimension reduction space for functional and high-dimensional data
effective dimension reduction space high-dimensional data
2010/11/18
In this paper, we consider regression models with a Hilbert-space-valued predictor and a scalar response, where the response depends on the predictor only through a finite number of projections. The ...
Existence of Spherically Symmetric Initial Data with Zero Energy, Unit Mass, and Virial less than - 1/2 for the Relativistic Vlasov-Poisson Equation with Attractive Coupling
Zero Energy Unit Mass
2010/11/19
In a recent paper, Kiessling and Tahvildar-Zadeh proved that any spherically symmetric classical solution of the attractive relativistic Vlasov-Poisson equation launched by sufficiently regular initi...
Nonparametric estimation of genewise variance for microarray data
Nonparametric estimation genewise variance microarray data
2010/11/17
Estimation of genewise variance arises from two important applications in microarray data analysis: selecting significantly differentially expressed genes and validation tests for normalization of mi...
An adaptive algorithm for the cornea modeling from keratometric data
Zernike polynomials surface reconstruction surface modeling corneal irregularities
2010/12/15
In this paper we describe an adaptive and multi-scale algorithm for the parsimonious t of the corneal surface data that allows to adapt the number of functions used in the econstruction to the condit...
