Variational Inference in Nonconjugate Models

open access: yes, 2013
Mean-field variational methods are widely used for approximate posterior inference in many probabilistic models. In a typical application, mean-field methods approximately compute the posterior with a coordinate-ascent optimization algorithm.

Sparsity Based Methods for Overparameterized Variational Problems

open access: yes, 2015
Two complementary approaches have been extensively used in signal and image processing leading to novel results, the sparse representation methodology and the variational strategy.

On a Variational Method for Stiff Differential Equations Arising from Chemistry Kinetics

open access: yesMathematics, 2019
For the approximation of stiff systems of ODEs arising from chemistry kinetics, implicit integrators emerge as good candidates. This paper proposes a variational approach for this type of systems.

Some Proximal Methods for Solving Mixed Variational Inequalities

open access: yesAbstract and Applied Analysis, 2012
It is well known that the mixed variational inequalities are equivalent to the fixed point problem. We use this alternative equivalent formulation to suggest some new proximal point methods for solving the mixed variational inequalities.

Quantum resources of quantum and classical variational methods

open access: yesMachine Learning: Science and Technology
Variational techniques have long been at the heart of atomic, solid-state, and many-body physics. They have recently extended to quantum and classical machine learning, providing a basis for representing quantum states via neural networks.

Some Implicit Methods for Solving Harmonic Variational Inequalities

open access: yesInternational Journal of Analysis and Applications, 2016
In this paper, we use the auxiliary principle technique to suggest an implicit method for solving the harmonic variational inequalities. It is shown that the convergence of the proposed method only needs pseudo monotonicity of the operator, which is a ...

Stability of solitary waves for a three-wave interaction model

open access: yesElectronic Journal of Differential Equations, 2014
In this article we consider the normalized one-dimensional three-wave interaction model $$\displaylines{ i\frac{\partial z_1}{\partial t}=- \frac{d^2z_1}{dx^2}- z_3{\bar z}_2\cr i\frac{\partial z_2}{\partial t}=- \frac{d^2z_2}{dx^2}- z_3{\bar z}_1 ...
