查询词典 data item

The soft-measuring technique is systemically described from the following aspects: auxiliary variable selection, data processing, soft-measuring model construction and model correction. Moreover, in order to solve the problem of measuring temperature of aluminum electrolytic cell, the importation electric power and blanking velocity are selected as auxiliary variable, then the temperature estimated value of the electrolytic cell is calculated.

Moreover, A hybrid algorithm, ALHybrid, which is made of the algorithm LIDBSO and the algorithm AprioriIpv, is designed. Two algorithm, MQC_Apriori and MQC_LIDBSO, are given to mining multiple level quantitative association rules with item constrains. Two algorithm, PMARⅡ and PMARⅢ, which are based on different sequential mining algorithms, are given for parallelling mining association rules. In order to solve the mining association rules problem when we add a set of data to a database or delete a set of data from a database, two incremental updating algorithm, EUAR and EUAR, are given. Three incremental updating algorithm for association rules mining, DIUAⅠ, DIUAⅡ and DIUAⅢ, are dedigned to solve the three kinds of association rules incremental updating problem in distributed databases.
