We propose a new framework for calibrating parameters of energy functionals, as used in image analysis. The method learns parameters from a family of correct examples, and given a probabilistic construct for generating wrong examples from correct ones. We introduce a measure of frustration to penalize cases in which wrong responses are preferred to correct ones, and we design a stochastic gradi...

In a graph, by definition, the weight of a (proper) coloring with positive integers is the sum of the colors. The chromatic sum is the minimum weight, taken over all the proper colorings. The minimum number of colors in a coloring of minimum weight is the cost chromatic number or strength of the graph. We derive general upper bounds for the strength, in terms of a new parameter of representatio...

determining production rate considering costs and revenues in order to maximize profit is one of the applied problems in small and medium size factories. mostly existing models in production planning consider production system statically and specify production rate, although the factors determining production rate include many different changes in practice. in fact, by increasing the production...

Design process is a key process in forming of product’s cost and if we notify to total design we will see all of the effective parameters in design activities. Design process is contented design planning, design inputs, design outputs, design review, design verification, design validation and design changes. This approach will help us to identify the cost parameters for managing, controlling an...
