A Variational Formulation for the Multilayer Perceptron [PDF]
, 2006 In this work we present a theory of the multilayer perceptron from the perspective of functional analysis and variational calculus. Within this formulation, the learning problem for the multilayer perceptron lies in terms of finding a function which is an extremal for some functional.

Aspects of the Schwinger multichannel variational formulation [PDF]
Physical Review A, 1988 We present a discussion which should be helpful in clarifying some key steps in the formulation of a multichannel extension of Schwinger’s variational principle for electron-molecule collisions [K. Takatsuka and V. McKoy, Phys. Rev. A 30, 1734 (1984)].

A Variational Principle for a Nonlinear Oscillator Arising in the Microelectromechanical System [PDF]
Journal of Applied and Computational Mechanics, 2021 A nonlinear oscillator arising in the microelectromechanical system is complex and it is difficult to obtain a variational principle. This paper begins with a wrong variational formulation and uses the semi-inverse method to obtain a genuine variational ...

A Variational Formulation for Discrete Registration [PDF]
, 2013 We present a novel variational formulation of discrete deformable registration as the minimization of a convex energy functional that involves diffusion regularization. We show that a finite difference solution (FD) of the variational formulation is equivalent to a continuous-valued Gaussian Markov random field (MRF) energy minimization formulation ...

Spectral discretization of the time-dependent Navier-Stokes problem with mixed boundary conditions
Advances in Nonlinear Analysis, 2022 In this work, we handle a time-dependent Navier-Stokes problem in dimension three with a mixed boundary conditions. The variational formulation is written considering three independent unknowns: vorticity, velocity, and pressure.

Existence Solution for a Non-smooth System [PDF]
Mathematics Interdisciplinary ResearchA variational method for a mixed boundary value problem in mathematical physics is considered. Using two-field Lagrange multipliers, we would investigate a variational formulation containing a mixed variational problem which is equivalent with a ...
