Black Box Variational Inference [PDF]

, 2013
Variational inference has become a widely used method to approximate posteriors in complex latent variables models. However, deriving a variational inference algorithm generally requires significant model-specific analysis, and these efforts can hinder ...

Casimir energy and variational methods in AdS spacetime [PDF]

, 2000
Following the subtraction procedure for manifolds with boundaries, we calculate by variational methods, the Schwarzschild-Anti-de Sitter and the Anti-de Sitter space energy difference.

Variational Methods and Planar Elliptic Growth [PDF]

, 2013
A nested family of growing or shrinking planar domains is called a Laplacian growth process if the normal velocity of each domain's boundary is proportional to the gradient of the domain's Green function with a fixed singularity on the interior.

Necessary conditions for variational regularization schemes

, 2013
We study variational regularization methods in a general framework, more precisely those methods that use a discrepancy and a regularization functional.

Variational methods for phononic calculations [PDF]

Wave Motion, 2016
Three fundamental variational principles used for solving elastodynamic eigenvalue problems are studied within the context of elastic wave propagation in periodic composites (phononics). We study the convergence of the eigenvalue problems resulting from the displacement Rayleigh quotient, the stress Rayleigh quotient and the mixed quotient.

Stochastic variational inference for large-scale discrete choice models using adaptive batch sizes

, 2015
Discrete choice models describe the choices made by decision makers among alternatives and play an important role in transportation planning, marketing research and other applications. The mixed multinomial logit (MMNL) model is a popular discrete choice

Variational approach to transport in quantum dots

, 2011
We have derived a variational principle that defines the nonequilibrium steady-state transport across a correlated impurity mimicking, e.g., a quantum dot coupled to biased leads.

Nonsmooth Lagrangian mechanics and variational collision integrators [PDF]

, 2003
Variational techniques are used to analyze the problem of rigid-body dynamics with impacts. The theory of smooth Lagrangian mechanics is extended to a nonsmooth context appropriate for collisions, and it is shown in what sense the system is symplectic ...

Variational methods in relativistic quantum mechanics

, 2007
This review is devoted to the study of stationary solutions of linear and nonlinear equations from relativistic quantum mechanics, involving the Dirac operator. The solutions are found as critical points of an energy functional. Contrary to the Laplacian
