Multi-source Information Fusion Based On Feature Discrimination

With the rapid development of Internet in China as the background of The Times,it is based on the characteristics of extensive information sources,large amount of information and high uncertainty of information,which are often encountered in the process of fusion,and focus on the integrated application and fusion method of multisource information.The principle and characteristics of information are selected for systematic research,and a conflict evidence correction method based on D-S evidence theory is proposed.Firstly,it overviews the difficulties in information processing and integration in the network information age,proposes the multi-source information fusion technology,summarizes the research status of multi-source information fusion at home and abroad,puts forward multi-source information fusion on the basis of the discrimination of information characteristics to support for system decision-making.Secondly,it mainly studies relevant concepts such as information?information classification and information fusion,introduces the mainstream in information fusion frame type and technology,leads out the basic theory and application mode of D-S evidence theory and indicates the defects of Dempster synthesis in high conflict for purpose on the convenience for further correction and improvement.Furthermore,in the study of D-S evidence theory multi-source information fusion,BPA is constructed by the fusion method in the form of information of basic probability assignment function based on the complexity and randomness of extraction.Finally,conflict is effectively identified based on D-S evidence theory,and new definition and measurement factors of evidence conflict are given through several measurement methods of evidence conflict.BY defining the evidence trust,the evidence is divided into three trust zones.On the basis of judging the high?moderate or low level of conflict,a new idea of evidence conflict identification for each interval is given,which makes the identification scope wider,the measurement more reasonable and the disposal more effective in the evidence conflict in the system.Figure 14;Table 4;Reference 44...
