It is difficult to analyze atmosphere laser communication channel(ALCC) under rainy condition with traditional mathematics methods. Weights feature extracting technology(WFET), as a novel data analysis tool to extract training data sets' feature information from weight sets in the trained multi-layer perceptron network(MLPN), is proposed, which can achieve in-depth analysis in data sets. Firstly,...
Most of the incremental association rule mining methods must rerun through processed data and have not made the best of the given rules. In this paper we propose an incremental association rules algorithm, this algorithm applies artificial immune theory and takes advantage of the given rules produced by original data set. Based on the quickly response during the memory cell recognizing the antigen,...
News reports in TV provide important and timely information about the city and the world to citizens. Moreover, data mining and indexing of news video clips provide a good source of information. However, news video usually consists of more than one news story. One must split them into individual news before indexing. Owing to the nature of news reports, the news anchorperson usually appears in the...
Based on environmental economics literature review and in-depth analyses, this paper identified five rules to evaluate environmental externality of emission sources, which are current environmental condition, amount of people injured, economic development level, physical geography characters, and natural scenery and cultural heritage. Under the framework of analytic hierarchy process (AHP), this paper...
Many scholars have studied the optimum exploitation sequence of the exhaustible resource, but one of its common characteristics is to establish a planning model and to seek the optimum solution under different bound conditions. This paper establishes a model from the angle of information searching and reveals the motives of the arrangement of exploitation sequence for the contemporary people. This...
Based on virtual team critical success factors (CSFs) analyses, this paper identified five rules that have significant influence on virtual team operational performance. The five rules are common objective, IT skills, members' attributes, leadership, and communication capacity. Each rule was scored on the basis of questionnaire survey. Then, under the framework of analytic hierarchy process (AHP),...
A large amount of data has accumulated in teaching appraisal that must be done every semester among most universities. In order to find out the law or model hidden in these data, the data mining technology should be used fully. This thesis introduces the application of association rules mining in the teaching appraisal, which can effectively guide the teaching work by finding out the intrinsic association...
An algorithm for distributed mining association rules with constraints called DMCASE is presented using Sampling and constraint-based Eclat algorithm. At each database site, sampling algorithm and constraint-based Eclat algorithm are implemented. And the local frequent itemsets satisfying constraints are developed. They then are combined to global frequent itemsets satisfying constraints based on...
