The method merges areas from the top down . neither it divides the area , nor it uses the recursion procedure that often used in entropy discretization . and further , it avoids the process of trying to find the split point using very values 該方法至下而上地合并區(qū)間,不分解區(qū)間,也不采用熵的離散化方法所用的遞歸進(jìn)程,更避免了熵方法中必須對每一個值進(jìn)行試探來選擇分割點(diǎn)的弱點(diǎn)。
