| In 1991 the idea that the apparatus of Generalized Nets (GNs, see [A1, 7
| |
| A3, A4]) can be used as a mathematical foundation of the Artificial
| |
| Intelligence (AI) was introduced (see [8]). During the last years, a lot of
| |
| results were obtained and a lot of papers and books were published connected
| |
| to the realization of this idea. Already, there are GN-models describing the
| |
| way of functioning and the results of the work of separate types of
| |
| databases and expert systems. The separate types of genetic algorithms and
| |
| of ant collony optimizations are described by GNs. The processes of pattern
| |
| and speech recognition and of scene analysis also are represented by GNs. There are GNs describing the processes of machine learning and of decision making, of intellectual games functioning, etc
| |
| (see, e.g., [12,16,A6,A7,A8,A9,A10,A11,A12]).
| |
|
| |
|
| Now it is clear that the GNs are not only a tool for modelling of processes,
| |
| but a methodology for their description, simulation and (that is the most
| |
| import) extension. After describing of the expert system by a GN, there was
| |
| shown that the concept of an expert system can be extended with new
| |
| components, so that from one side the new expert system also to be modelled
| |
| by a GN, and from another hand, the new expert system to have essentially
| |
| new components. For example, expert systems with priorities of their facts
| |
| and roles were introduced. Expert systems with special meta-facts, that
| |
| change the rules, but that are essentially more suitable for applying were
| |
| constructed. As extensions of fuzzy expert systems, intuitionistic fuzzy
| |
| expert systems were defined. Expert systems that can answer to temporal and
| |
| modal questions were described.
| |
|
| |
|
| |
| In the present book the authors collect a part of their research in the area
| |
| of Neural Networks (NNs). Here we construct GNs representing the way of
| |
| functioning and the results of the work of separate types of NNs. Also, we
| |
| describe feedforward types of NNs as multilayer perceptron (MPL) by GNs. Here, we
| |
| give GNs that determine the optimal forms of NNs and MPL using golden
| |
| sections algorithm. The possibility of the parallel work and transfer of information
| |
| among a lot of NNs, but in the frames of one GN is discussed.
| |
|
| |
| The first attempts to represent NNs by GNs were done 15-20 years ago (see [A13,A14,A15,A16,A17]), but the systematic research started in the joint research of the authors. Here and in another book, we will collect all our research devoted to NNs and GNs. In the second book, that we plan to prepare in a near time, we will discuss the program realization of the GN-models, described here.
| |
|
| |
| So, we like to show that the apparatus of the GNs is a suitable tool for
| |
| modelling of NNs and of studying of NN behaviour.
