A New Study of DSS Based on Neural Network and Data Mining Xianyi Qian Xianjun WangSchool of Electronic Information & Electric Engineering School of Electronic Information & Electric Engineering Changzhou Institute of Technology Changzhou Institute of Technology Changzhou, China Changzhou, China hbxfqxyqxy_123@163.comAbstract—Authors have studied a new method in which DSS hasbeen supported based on neural network and data mining. There II. INTELLIGENT DECISION SUPPORT SYSTEMare three subjects which have been studied in the paper. How to As shown in Fig. 1, it is the general configuration of DSS.make use of neural network to support DSS is the first. The There are three departments of DSS. They are language systemsecond is how to make use of data mining to support DSS. And (LS), problem process system (PPS) and knowledge systemthe third is how to make use of neural network and data mining (KS). Problem process system is composed of reasoningto support DSS. Authors presented and answered some questions system (RS), model base management system (MBMS),of study of DSS. And we studied the principle of supporting DSSbased on neural network and data mining. The application of knowledge base management system (KBMS) and data baseIDSS based on neural network and data mining in making use of management system (DBMS). Knowledge system is composedenergy and protection of resources have been worked out in the of model base (MB), knowledge base (KB) and data base (DB).end. [2] Keywords-Neural Network; Data Mining; DSS; counterspreading I. INTRODUCTION DSS was brought forward first in 1970s by Americanscientist Scott Morton. And it had a great development in1980s. A new subject and study has been produced. Itsfunctions are the integration of making use of mass data, theorganization of many patterns and the realization of scientificdecision by assistance of all directors through man-machinealteration system. Intelligentizing is one of the developmentaldirections of the study of DSS. Neural network is a highly nonlinear constant time powersystem with super great scale. Its main specials are thecomplete function of network, the ability of paralleldistributing process with super great scale, the highly robustquality and the ability of learning and associating. And it is ofthe common as same as the ordinary nonlinear system. These Figure 1. Configuration Block Drawing of DSSare attractability, dissipation, non-balance, non-reversibility,many factors, wide connection and adaptability. It is a top Although there is a great development of the applicationcrossing subject which is of wide application. And the study of and theory of DSS, there is a great counterwork of DSSIDSS based on neural network is of great application valve of because of the processing of serial program symbol. The mainpractice and theory. It is one of the latest studies of DSS. problems of DSS are as following. Data mining is knowledge discovery in database. It is a 1)Bottle-neck of knowledge learning.

It is that data which knowledge engineers transplant the expert knowledge tomining is the mining of knowledge among the mass data. computer.

As shown in Fig. 2, a intelligent decision support system ofneural network is composed of knowledge, data and model. Itis of main four sub-systems, neural network, reasoning system,data mining system of neural network and natural languagealteration system. [3] Figure 3. Configuration Drawing of CP Network There are two kinds of data mining which are directly data mining and indirectly data mining. The aim of directly data mining is that a model is built up by means of available data and a special variable is described. The definition of indirectly data mining is that no some real variable is described with a model but some kind of relationship has been built up. [4] B. Reasoning of Neural Network Figure 2. Block Drawing of IDSS of Neural NetworkA. Data Mining of Neural Network Data mining of neural network is a data mining mode basedon neural network technology. There are five basic tasks ofdata mining, relative analysis, clustering, concept description,error monitoring and forecast. The forward feeding neuralnetwork, for example BP network, is usually worked in concept Figure 4. Sketch Map of Repeat Reasoning of Neural Networkdescription and forecast. The counter spreading (CP) neuralnetwork can be worked in statistics analysis and clustering. As The main research of neural network system is the doubleshown in Fig. 3, it is a configuration drawing of CP network directions reasoning method based on the data driving and aimwhich created by American neural calculating expert Robert driving of neural network. Reasoning is the main method ofHecht-Nielsen solutions. The course of knowledge reasoning is the process of solutions. There are some problems such as “assembled blast”

Man-machine Alteration SystemThe parallel processing of neural network is the best method of The alteration structure has been established by man-solving above problems. An explanation of reasoning course of machine alteration system which has input and output betweendouble directions associate memory (BAM) network is shown system and user. Man-machine alteration system is thein the next. As shown in Fig. 4, the first arrangement of repeat important part of IDSS which is of all functions as shown inreasoning of neural network is of no calculate function, but of Fig. 5.fan-out function which is distributed the output to input. Aninput vector A is applied up to power matrix and an outputvector B is turn out. And vector B is applied to the turn matrixWT of power matrix W, then a new output vector A is turnout. The course is repeated until a steady point of networkwhich A and B are constant. The steady point is called ashomeostasis. [5] There is a formula of the repeat course as following. B=F(AW) (1) A=F(BWT) (2) A is output vector of the first arrangement, herein, B isoutput vector of the second arrangement, W is the powermatrix between the first arrangement and the second, and F ispower function. [6] Equation (1) can be used to fulfill the reasoning of datadriving and Equation (2) can be used to fulfill the reasoning of Figure 5. Configuration of IDSS Based on Neural Network and Data Miningaim driving. Double directions reasoning can be realized byhomeostasis of BAM. The homeostasis is the crossing point ofdata driving and aim driving of BAM. And it is the decision B. Neural Network, Data Mining, Solutionssolution. Neural network, data mining and solutions include two modules which are solutions module and data mining module.C. Natural Language Alteration System of Neural Network Data mining module works up in order to gain knowledge The main research of natural language process (LS) is the needed through making use of the model of models base,syntax analysis and meaning analysis based on neural network. method of methods base and knowledge of knowledge base.Natural language is belonged to non-numerical valve symbol Solutions module works up in order to configure or half-which is symbol flow with different numbers. It is of its own configure the problems through making use of thesyntax and means system and its data structure, means corresponding model of models base, method of methods base,expression and calculation rules are rather different from knowledge of knowledge base and data of data base.
