In this paper, an improved decision tree algorithm based on dispersion measure of attribute information was proposed, which combined information gain and dispersion of attribute information as an evaluation criterion of attribute selection in order to overcome the deficiency that ID3 decision tree algorithm leaned to the multi-value attribute. From results of the experiment, it can be demonstrated...
Aiming at the difficulty of large weapon equipment operation training simulation, GL Studio software tool was adopted based on VR technology. A hierarchy structure was put forward to simulate all kinds of integrating equipment system, single equipment and operation unit. Key technologies including Model database structure optimization, LOD, operation unit motion simulation based on DOF and screen...
The general design of HLA based communication command equipment operation simulation system is given to solve the difficulty of large equipment operation training. Firstly, the simulation system and its constitution are introduced. Secondly, two different federation runtime structures including single federation basic structure and multiple federations structure are designed according to system architecture...
We used the statistical sampling method to analyze the relation between the university teachers' network class upload quantity, visit quantity and university teachers' four personality characteristics: gender, age and title. Therefore universities should take the teachers' personality characteristics into account to adopt the effective measures for universities networking education building. University...
The current military simulative training didn't consider the impact of battlefield communication network well, so it can't meet the requirement of future development. To solve this problem, the paper put forwarded the new idea of military simulative training based on "network in the loop". Through the utilizing of high level architecture (HLA), network simulation technology and etc, we embedded...
This paper try to design structure of Web-based service management of social network. The structure integrating IT service and social network service flow. Help desk becomes only interface for all levels of users according to their individual demands. Though analysis of service events and user's feedback in service flow, it also provides the decision-making to improve the quality of Web-based service...
