Using the Continuous Spectrum to “Feel” Integrability: the Effect of Boundary Conditions
Test model integrability partial differential differential difference equations of continuous spectrum
2014/12/29
The scope of this work is to propose a method for testing the integrability of a model partial differential (PDE) and/or differential difference equation (DDE). For monoparametric families of PDE/DDE’...
Independent Vector Analysis: Identification Conditions and Performance Bounds
Independent Vector Analysis Identification Conditions Performance Bounds
2013/5/2
Recently, an extension of independent component analysis (ICA) from one to multiple datasets, termed independent vector analysis (IVA), has been the subject of significant research interest. IVA has a...
We show that numerical data assimilation is feasible in principle for an idealized model only if an effective dimension of the noise is bounded; this effective dimension is bounded when the noises in ...
Identification and well-posedness in nonparametric models with independence conditions
Identification well-posedness nonparametric models independence conditions
2012/11/22
This paper provides a nonparametric analysis for several classes of models, with cases such as classical measurement error, regression with errors in variables, factor models and other models that may...
Revealing Sub-Optimality Conditions of Strategic Decisions
Strategic decision making Fitness landscape theory
2011/7/19
Conceptual view of fitness and fitness measurement of strategic decisions on information systems, technological systems and innovation are becoming more important in recent years.
Tight conditions for consistency of variable selection in the context of high dimensionality
variable selection nonparametric regression set estimation sparsity pattern
2011/7/6
We address the issue of variable selection in the regression model with very high ambient dimension, i.e., when the number of variables is very large. The main focus is on the situation where the numb...
On statistical properties of sets fulfilling rolling-type conditions
r-convexity positive reach rolling condition Glivenko-Cantelli classes set estimation boundary length excess mass
2011/6/20
Motivated by set estimation problems, we consider three closely related shape conditions
for compact sets: positive reach, r-convexity and rolling condition. First, the
relations between these shape...

Living conditions：classification of households using the Kohonen algorithm
Living conditions classification households Kohonen algorithm
2010/4/27
In the analysis of poverty and social exclusion, indicators of living conditions are some interesting non-monetary complements to the usual measurements in terms of current or annual income. Living co...
Necessary and sufficient conditions for extended convergence of semimartingales
Necessary and sufficient conditions extended convergence of semimartingales
2009/9/23
The extended convergence (in sense of Aldous [I]) of
processes with filtrations is considered. There are examined the
cases where the well-known conditions, sufficient for the weak
convergence of s...

Conditions for convergence of number of crossings to the local time。
Equivalent conditions for the consistency of nonparametric spline density estimators
Equivalent conditions the consistency of nonparametric spline density estimators
2009/9/23
We study the nonparametric spline density estimators of
probability density. The equivalence of weak convergence for L,-consistency
of one density and completely for L,-consistency of all
densities...
On some moment conditions for sums of independent random variables
some moment conditions sums of independent random variables
2009/9/23
Some moment bounds and conditions for sums of
independent random variables are considered. In particular, a method
is presented to estimate the absolute moments using the related
characteristic fun...
Upper bounds for the expected Jefferson rounding under mean-variance-skewness conditions
Gain of rounding JeEerson rounding geometric moment theory four-dimensional geometry
2009/9/22
For the class of nonnegative random variables with
given mean, variance, and skewness and support bound, we present
a sharp upper bound for the expectation of rounding due to the Jefferson
rule. Th...
