THE USE OF BAYESIAN NETWORKS FOR THE DEVELOPMENT OF EXPERT SYSTEMS

When making important decisions, it is prudent to seek advice from others who have expertise in the relevant field or domain of knowledge. These experts or consultants base their advice on accumulated knowledge, experience and any other available source of information. There is considerable interest in automating this human reasoning process. Such automated systems, known as expert systems, model the knowledge domain of interest and its relationship with the available data. Current approaches to expert systems include rule–based, decision tree and artificial neural network representations for modeling the knowledge, and density estimation, classification, regression and clustering techniques for analyzing these models. A Bayesian belief network is a graphical representation of a probabilistic dependency model. It consists of a set of interconnected nodes, where each node represents a variable in the dependency model, and the connecting arcs represent the causal relationships among these variables. Each node or variable may take on one of a number of possible states or values. The belief in, or certainty of, each of these states is determined from the belief in each possible state of every node directly connected to it and its relationship with each of these nodes. The belief in each state of the node is updated whenever the belief in each state of any directly connected node changes. Belief networks are graphical models that effectively model the knowledge domain as opposed to rule- based systems that model the expert. They provide a useful tool for inferring hypotheses from the available information by transmitting probabilistic information from the data to various hypotheses. The Bayesian belief networks are graphical models that use Bayesian probabilities to model the dependencies within the knowledge domain. They are used to determine or to infer the posterior marginal probability distributions for the variables of interest. As such, they do not include decisions or utilities that represent the preferences of the user, rather it is left to the user to make decisions based on these probability distributions. The causal relationships in the Bayesian belief networks allow the correlation between variables to be modeled and predictions to be made, even when direct evidence or observations are unavailable. Bayesian belief networks also blend prior knowledge with the data through the use of both prior and conditional probabilities. These characteristics of Bayesian belief networks give them an advantage over classical probability techniques.

Keywords: Bayesian belief network, probabilistic model, probability language, expert system, hypothesis node, dependency models.

Internet - PR is an important part of any company's PR. Public relations have a lot of advantages, for example: promptness, as well as interactivity is an important part of PR. If we take, for example: TV, which has a great impact on the society, recent attempts to establish feedback from the stands of the programs with telephone interactive surveys should be noted. The Internet is comfortable to use, contains a vast amount of information, it may be a large amount of useful information. These qualities make it an effective means for promotion. Another advantage of the Internet is democracy and protection of network etiquette, which is reflected in the success of your company's reputation and you will succeed and develop in a virtual world, it is so important for the realization of the Internet PR.

THE INTERNET AS A MEDIUM OF PR REALIZATION AND TOOL

Prangishvili A.I., Kvirikashvili S.G. and Namicheishvili O.M.

Georgian Technical University

The Internet acts as a vehicle for communication and unconventional channel , which is characterized by the lack of central organization structure. The Internet is a global virtual electronic marketplace, which has no territorial or time limits, it is a fact that the absence of censorship is profitable in the dissemination of information. A similar mechanism is effective to conduct PR company with using psychotechnology. As for the PR methodology, the Internet can be divided as follows: mass relations, group relations, media relations. All of them have different goals and create a strong PR tool.

Abstract. The article deals with the method of face recognition used in cybernetics. It is based on the consideration of the psychic phenomena, in particular, hierarchy of reasoning by using the principal stages of reasoning. Face recognition, identification of the similarity between the things or pieces of information and their common features, fixing them and applying them to new things is a complex process needing human reasoning, as man cannot realize other forms of intelligent life. The spectrum of features demonstrates that the recognition (identification in our case), is given as portions, like in the case of manifestation of quantum phenomena, i.e. the information is recognized.
