decision tree analysis method
Vertaling van "decision tree analysis method" in Chinees
决策树分析方法
Compared with a conventional logistic regression algorithm, the decision tree analysis method acquires a more accurate result based on service explanation.
采用决策树分析方法相比传统的逻辑回归算法，根据有业务解释性，即得到的结果更准确。
A method of verifying the pre-constructed type models corresponding to different user data is not specifically limited by the embodiment, and includes but is not limited to a decision tree analysis method.
关于对预先构建的不同用户数据对应的类型模型进行验证的方法，本实施例不作具体的限定，包括但不限采用决策树分析方法。
Wherein the decision tree analysis method means deriving two or more events or different results when analyzing each decision or event (namely in a natural state), and drawing branches of the decision or event on a figure.
其中，决策树分析方法是指分析每个决策或事件（即自然状态）时，都引出两个或多个事件和不同的结果，并把这种决策或事件的分支画成图形
When the pre-constructed type models corresponding to different user data are verified with the decision tree analysis method, a user group including a certain number of users is pre-selected and is randomly divided into three parts.
在采用决策树分析方法对预先构建的不同用户数据对应的类型模型进行验证时，预先选取包含一定数量用户的用户群，将用户群随机分成三部分
Specifically, when the pre-constructed type models corresponding to different user data are verified with the decision tree analysis method, 1 million of users, for instance, are selected, the division ratio of the user group is the same as the above ratio, the user number in the training set is 400,000, the user number in the verification set is 300,000 and the user number in the test set is 300,000.
具体地，在采用决策树分析方法对预先构建的不同用户数据对应的类型模型进行验证，以筛选100 万用户，用户群的划分比例与上述比例相同为例，则训练集中的用户数量为40 万，验证集中的用户数量为30 万，测试集中的用户数量为30 万。
The figure is just like branches and trunk of a tree and is thus called as the decision tree analysis method.
这种图形很像一棵树的枝干，故称决策树分析法。
