Response including some parameters attribute - value pairs that grants access to the user 回應(yīng),其中包括一些參數(shù)(屬性-值對) ,以保證對該用戶的存取。
To solve this problem , we present a new approach on ids algorithm - the information gain of attribute - value pairs in two levels - to optimize the decision tree 為了解決取值偏向的問題,本文在id3算法的基礎(chǔ)上提出了屬性-值對的兩次信息增益優(yōu)化算法。
We also took tests to compare our optimization algorithm with id3 algorithm using the data set famn providing , and did experiment on the standard data uci providing , the result show that the information gain of attribute - value pairs in two levels optimization algorithm is more excellent than ids algorithm indeed 通過對使用同一個實例集用不同的算法建立的決策樹的分析比較,得出使用屬性-值對的兩次信息增益優(yōu)化算法比id3算法所得到的決策樹更理想。并且通過對famn家族數(shù)據(jù)集的測試比較以及對uci提供的標(biāo)準(zhǔn)數(shù)據(jù)進行實驗,說明了這種算法確實比id3算法有所改進。
