Loopy Belief propagation(LBP) is a technique for distributed inference in performing approximate inference on arbitrary graphical models. In this paper, we propose an extended influence diagram with loopy belief propagation technique to solve the advanced decision making problems, especially the multi-criteria decision making(MCDM) in term of uncertain criteria. When a number of nodes is increasing in the network, solving for exact solutions and making optimal decision becomes complicated and time consuming. The belief propagation is an efficient way to solve inference problems by propagating local messages around neighborhoods. In this paper, we will focus on the principle of loopy belief propagation, and its applications in advanced decision making problems. Loopy belief propagation is another choice for solving the advance decision making problem in order to get approximate solution and is selected to present in this paper. A solution is approximated which a high probability action under the preference criteria and high utility. In addition, the comparison between the loopy belief propagation method including other approximated method and the exact methods based on the prediction and the running time is shown in this research.
We construct a Bayesian model that integrates top-down with bottom-up criteria, capitalizing on their relative merits to obtain figure-ground segmentation that is shape-specific and texture invariant. A hierarchy of b...

The availability of new large-address-space computers has provided us an opportunity to examine techniques for transferring programming systems, and in particular, Usp systems, to new computers. We contrast two approaches: designing and building a Virtual Machine implementation of Lisp, and (re)writing the system in a "portable" programming language ("C"). Our conclusion is that the latter approach may very well be better.

We describe a programming environment which combines the Macsyma algebraic manipulation system with convenient and direct access to numeric Fortran run-time libraries. With this system it is also convenient to generate, compile, load, and invoke totally new Fortran programs which may have been produced by combining algebraically derived formulas and program "templates". These facilities, available on VAX-11 computers, provide an environment for the generation and testing of advanced scientific software. Enhancements of Fortran for high-precision calculations, interval arithmetic, and other purposes are also supported.

Algebraic manipulation systems such as MACSYMA include algorithms and heuristic procedures for indefinite and definite integration, yet these system facilities are not as generally useful as might be thought. Most isolated definite integration problems are more efficiently tackled with numerical programs. Unfortunately, the answers obtained are sometimes incorrect., in spite of assurances of accuracy;furthermore, large classes of problems can sometimes be solved more rapidly by preliminary algebraic transformations. In this paper we indicate various directions for improving the usefulness of integration programs given closed form integrands, via algebraic manipulation techniques. These include expansions in partial fractions or Taylor series, detection and removal of singularities and symmetries, and various approximation techniques for troublesome problems.
The question as to the correct block exit strategy, retention or deletion, is resolved by formally comparing the contour model and the stack model, each of which implements one of the strategies, to the copy rule, a f...
