On model selection consistency of M-estimators with geometrically decomposable penalties
model selection consistency M-estimators geometrically decomposable penalties
2013/6/14
Penalized M-estimators are used in many areas of science and engineering to fit models with some low-dimensional structure in high-dimensional settings. In many problems arising in bioinformatics, sig...
On the Convergence and Consistency of the Blurring Mean-Shift Process
Mean-shift Convergence Consistency Clustering,γ-divergence Super robustness
2013/6/13
The mean-shift algorithm is a popular algorithm in computer vision and image processing. It can also be cast as a minimum gamma-divergence estimation. In this paper we focus on the "blurring" mean shi...
The Lasso is a popular statistical tool invented by Robert Tibshirani for linear regression when the number of covariates is greater than or comparable to the number of observations. The validity of t...
The subset argument and consistency of MLE in GLMM: Answer to an open problem and beyond
Cramer consistency crossed random effects MLE GLMM,salamander mating data subset argument Wald consistency
2013/4/27
We give answer to an open problem regarding consistency of the maximum likelihood estimators (MLEs) in generalized linear mixed models (GLMMs) involving crossed random effects. The solution to the ope...

2011/6/20
This paper addresses the estimation of the nonparametric conditional moment
restricted model that involves an infinite dimensional parameter g0. We
estimate it in a quasi-Bayesian way based on the l...
Consistency of maximum-likelihood and variational estimators in the Stochastic Block Model
maximum-likelihood Stochastic Block Model
2011/6/17
The stochastic block model (SBM) is a probabilistic model de-
signed to describe heterogeneous directed and undirected graphs. In this
paper, we address the asymptotic inference on SBM by use of max...

On the consistency of Fréchet mean in deformable models for curve and image analysis
Mean pattern estimation Fr´ echet mean Shape analysis Deformable models
2010/10/14
A new class of statistical deformable models is introduced to study high-dimensional curves or images. These models are useful to analyze the geometric modes of variation of a data set around a commo...

2009/9/23
We study the nonparametric spline density estimators of
probability density. The equivalence of weak convergence for L,-consistency

The asymptotic consistency and efficiency fixed-size sequential confidence sets
2009/9/22
In the paper, a sequential confidence set based on an
estimation process of a multivariate parameter is constructed. Under
the assumption that the estimation process scaled by an increasing

2009/9/22
A large number of statistical models is described by
a family of reversed submartingales converging to degenerated limits.
The problem under consideration is to estimate the maximum points

Consistency and Identifiability Revisited。
Consistency of support vector machines for forecasting the evolution of an unknown ergodic dynamical system from observations with unknown noise
Observational noise model forecasting dynamical systems support vector machines consistency
2010/4/30
We consider the problem of forecasting the next (observable)
state of an unknown ergodic dynamical system from a noisy observation
of the present state. Our main result shows, for example, that
