Convergence properties of a general algorithm for calculating variational Bayesian estimates for a normal mixture model
Mixture model Variational Bayes Local convergence Laplace approximation
2009/9/21
In this paper we propose a generalised iterative algorithm for calcu-
lating variational Bayesian estimates for a normal mixture model and investigate
its convergence properties. It is shown theoret...
SECOND-ORDER CONVERGENCE PROPERTIES OF TRUST-REGION METHODS USINGINCOMPLETE CURVATURE INFORMATION, WITH AN APPLICATION TO MULTIGRID OPTIMIZATION
Nonlinear optimization Convergence to local minimizers Multilevel problems

Convergence properties of trust-region methods for unconstrained nonconvex
optimization
is considered in the case where information on the objective function's local
curvature is incomplete, in the...
Convergence Properties of the Dependent PRP Conjugate Gradient Methods
Conjugate gradient convergence property
2007/8/7
In this paper, a new region of βk with respect to βkPRP is given. With two Armijo-type line searches, the authors investigate the global convergence properties of the dependent PRP conjugate gradient ...
CONVERGENCE PROPERTIES OF CONJUGATE GRADIENT METHODS WITH STRONG WOLFE LINESEARCH
Conjugate gradient algorithms global co
2007/8/7
In this paper, we investigate the convergence property of the conjugate gradient algorithms which depend on the search directionsd_1=-g_1, d_{k+1}=-g_{k+1}+\beta_k d_k ,k\geq 1, by using different cho...
This paper presents a new conjugate gradient method for unconstrained optimization. This method reduces to the Polak-Ribiere-Polyak method when line searches are exact. But their performances are diff...
CONVERGENCE PROPERTIES OF MULTI-DIMENSIONAL NEAREST NEIGHBOR DENSITY ESTIMATES FOR THE CASE OF GENERAL KERNEL

2007/8/7
In this paper we give weaker conditions to ensure the strong uniform consis-tency of multi-dimensional nearest neighbor (N.N.) estimates with non-uniform kernel and obtain the convergence rates of the...
