摘要: 該文提出一種新的基于構(gòu)造性覆蓋算法的知識發(fā)現(xiàn)方法。由于覆蓋網(wǎng)絡(luò)構(gòu)造方法的特殊性，使得形成的每個覆蓋領(lǐng)域都很有價值，對覆蓋領(lǐng)域內(nèi)樣本分析能挖掘出數(shù)據(jù)內(nèi)在的知識，且可以根據(jù)需求構(gòu)造不同的覆蓋網(wǎng)絡(luò)，形成對數(shù)據(jù)的多側(cè)面的分析；實(shí)驗結(jié)果表明覆蓋算法用于知識發(fā)現(xiàn)的方法是有效可行的。

Abstract: This paper proposes a new method of knowledge discovery based on the structured covering algorithm. Since the network of covering domains is constructed through a special method, it makes each covering domain a valuable pattern. Through analyzing the samples covered by the covering domain, certain valuable pattern will be found, which includes clustering information of samples, association rules among the data, the outlier analysis, etc. And in order to meet different requirement of users, different covering networks can be structured, therefore, multi-sides of data can be analysed. The experiments show that using the covering algorithm to discover knowledge of data is effective and feasible. -
