Real world data sets usually have many features, which increases the complexity of data mining task. Feature selection, as a prepro-cessing step to the data mining, has been shown very effective in reducing dimensionality, removing irrelevant data, increasing learning accuracy, and improving comprehensibility. To find the optimal feature subsets is the aim(More)
Software systems are faced with serious dependability crisis. It brings out a series of software dependability related research areas and the trusted software testing process is one of the core issues. In order to conduct the trusted software testing research, a high priority issue to be solved is how to create a formal model of software testing describing(More)
Time series composed of a series of data observed according to time sequence. There are large numbers of time series in the field of automatic control. Usually time series data is massive. Sometimes, it is inefficient or impractical to mine the original time series data directly. So time series should be represented on higher level. Piecewise Linear(More)
Traditional fuzzy reasoning methods have two problems 1) the operators appearing in the fuzzy reasoning methods are fixed; 2) how to select the operations for the reasoning methods. In order to solve the problems, we propose the updating fuzzy reasoning method based on universal logic in this paper. The reasoning rules based on universal logic of five fuzzy(More)
