Approximate inference techniques with expectation constraints [PDF]

Journal of Statistical Mechanics: Theory and Experiment, 2005
This paper discusses inference problems in probabilistic graphical models that often occur in a machine learning setting. In particular it presents a unified view of several recently proposed approximation schemes. Expectation consistent approximations and expectation propagation are both shown to be related to Bethe free energies with weak consistency

Approximation with interpolatory constraints

Journal of Mathematical Analysis and Applications, 1978
AbstractBest approximation with interpolatory constraints is considered. A sufficient condition for an approximating function to be a unique best approximation is presented. A necessary condition is deduced if uniqueness holds.

Approximation algorithms for channel assignment with constraints

Theoretical Computer Science, 1999
Cellular networks are generally modeled as node-weighted graphs, where the nodes represent cells and the edges represent the possibility of radio interference. An algorithm for the channel assignment problem must assign as many channels as the weight indicates to every node, such that any two channels assigned to the same node satisfy the co-site ...

STABILITY OF MOTION OF RAILWAY VEHICLES DESCRIBED WITH LAGRANGE EQUATIONS OF THE FIRST KIND

Nauka ta progres transportu, 2018
Purpose. The article aims to estimate the stability of the railway vehicle motion, whose oscillations are described by Lagrange equations of the first kind under the assumption that there are no nonlinearities with discontinuities of the right-hand sides.

Finite-Dimensional Gaussian Approximation with Linear Inequality Constraints [PDF]

SIAM/ASA Journal on Uncertainty Quantification, 2018
Introducing inequality constraints in Gaussian process (GP) models can lead to more realistic uncertainties in learning a great variety of real-world problems. We consider the finite-dimensional Gaussian approach from Maatouk and Bay (2017) which can satisfy inequality conditions everywhere (either boundedness, monotonicity or convexity).

A cost function approximation method for dynamic vehicle routing with docking and LIFO constraints

Multimodal Transportation
In this paper, we study a dynamic pickup and delivery problem with docking constraints. There is a homogeneous fleet of vehicles to serve pickup-and-delivery requests at given locations.

Study on multi-objective nonlinear programming in optimization of the rough interval constraints

International Journal of Industrial Engineering and Production Research, 2018
This paper deals with multi- objective nonlinear programming problem having rough intervals in the constraints. The problem is approached by taking maximum value range and minimum value range inequalities as constraints conditions, reduces it into two ...

Optimization for Nonlinear Uncertain Switched Stochastic Systems with Initial State Difference in Batch Culture Process

Complexity, 2019
Based on the deterministic description of batch culture expressed in form of switched ordinary differential equations, we introduce a switched stochastic counterpart system with initial state difference together with uncertain switching instants and ...
