The Ways of Improving Associative Properties of Neural Network Mathematical Models in the System of Taxation Management and Control

The purpose of the research is the problem of providing associative properties of neural models for complex economic objects. The ideas suggested in the paper are connected essentially with the system of taxation management and control. The research is devoted to the problem of creating standard adaptive models of tax-paying enterprises. The main problem of the prediction model of stochastic object has been solved. Some suggestions on improving associative properties of neural network are formulated. A new principle of creating neural network model with good associative properties ≈ principle of generalized cross-confirmation is proposed. The principle is illustrated by a specific numeric example.

Multimodal Semantic Representation Based on Neuronetworks

The article gives an idea of multimodal model of human knowledge organization. It is shown that the model kernel consists of overmodal formations the organization principles of which can be explained by means of text information processing. There is a description of a statistical algorithm, which allows the automatic building of such formations from a large amount of text documents by using the hierarchical structure of dynamic neural networks. It is proved that over-modal formations built only on the basis of visual text modality are correct but not include another modal conceptions giving them sense on the physical level.

Logic Function Decomposition Algorithm Aimed at High-Performance Digital Units Synthesis
We present a BDD-based algorithm for logic function decomposition that is aimed at speed-up of digital units. For synthesis of carry circuits of arithmetic units we propose iterative use of the algorithm creating pyramidal structures out of initial linear representation. This improves circuit performance drastically, leading to novel improved arithmetic unit implementation.

Multicoloreul Pixel of the Printer

In the article the problems of the information technology of multicolorful printing are considered. In particular, the new model of a multicolorful pixel of the color printer is developed. The offered algorithms are intended for appropriate stages of multicolorful color separation and allow receiving materials for the comparison of the different color printers maintaining a dot output.
