Kernel density estimation via diffusion and the complex exponentials approximation problem
condensed density random matrices parabolic PDE
2012/6/21
A kernel method is proposed to estimate the condensed density of the generalized eigenvalues of pencils of Hankel matrices whose elements have a joint noncentral Gaussian distribution with nonidentica...
The lasso is a popular tool for sparse linear regression, especially for problems in which the number of variables p exceeds the number of observations n. But when p>n, the lasso criterion is not stri...
A procedure for the change point problem in parametric models based on phi-divergence test-statistics
Change point Information criterion Divergence Wald test-statistic General distributions
2011/8/25
Abstract: This paper studies the change point problem for a general parametric, univariate or multivariate family of distributions. An information theoretic procedure is developed which is based on ge...
Stable marriage problem under Monte Carlo simulations, influence of preferrence corelation on relaxation time
Stable marriage problem Monte Carlo simulations influence of preferrence corelation relaxation time
2011/7/5
In this paper we consider stable marriage problem under the Monte Carlo
simulations. We investigate how correlation in lists of preferrences can affect
simulation results such as: relaxation time, t...
Estimation of the mean of functional time series and a two sample problem
Functional data analysis Time series Two sample problem Long–run variance Eurodollar futures
2011/6/15
This paper is concerned with inference based on the mean function of a functional
time series, which is defined as a collection of curves obtained by splitting a continuous
time record, e.g. into da...
Ideal-adic semi-continuity problem for minimal log discrepancies
Ideal-adic semi-continuity problem minimal log discrepancies
2011/1/17
We discuss the ideal-adic semi-continuity problem for minimal log discrepancies by Mustat¸˘a. We study the purely log terminal case, and prove the semi-continuity of minimal log discrepanci...
The ultraviolet infrared mixing problem on the noncommutative Moyal space
ultraviolet infrared problem noncommutative Moyal space
2011/3/3
It is shown that the mixing of ultraviolet and infrared divergences in quantum field theory on Moyal space is not an artefact of the Euclidean framework, but occurs also in the Hamiltonian setting whe...
On the bifurcation and continuation of periodic orbits in the three-body problem
three body problem (TBP) periodic orbits bifurcations
2010/12/28
We consider the planar three body problem of planetary type and we study the generation and continuation of periodic orbits and mainly of asymmetric periodic orbits.
Nonsmooth Formulation of the Support Vector Machine for a Neural Decoding Problem
Nonsmooth Formulation the Support Vector Machine Neural Decoding Problem
2011/1/4
This paper formulates a generalized classification algorithm with an application to classifying (or `decoding') neural activity in the brain. Medical doctors and researchers have long been interested ...
Decay of Resonance Structure and Trapping Effect in Potential Scattering Problem of Self-Focusing Wave Packet
Quantum Gases (cond-mat.quant-gas) Exactly Solvable and Integrable Systems (nlin.SI)
2010/11/10
Potential scattering problems governed by the time dependent Gross-Pitaevskii equation are investigated numerically for various values of coupling constants. The initial condition is assumed to have t...
