新型偏好敏感决策树算法
Novel preference sensitive decision tree algorithm
摘要
Abstract
In view of the fact that the existing decision tree models have not considered the preference behavior of decision makers to results during the classification process,so that it cannot predict problems which have obvious preference problem very well.This paper proposed a new PSDT algorithm.The algorithm introduced the preference degree and preference cost.It constructed a new attribute selection factors (ASF)by taking attribute information and effective preference into account.Fur-ther more,the PSDT algorithm had the class label distribution rule of node based on effective preference.Finally,it generated a preference sensitive decision tree which had the best preference degree by adjusting the preference degree adaptively.The theoretical analysis and experimental results show that the algorithm can not only achieve the high precision prediction of pref-erence class,but also ensure the decision tree has good overall accuracy.And it has high validity and practicability.What is more,it can solve the decision problems in preference sensitive environment in a good method.关键词
