一种基于改进迭代决策树算法的目标威胁评估模型

A Target Threat Assessment Model Based on Improved Gradient Boosted Decision Trees

为了解决当前目标威胁程度评估的不足,完善威胁评估体系,在对目标威胁数据特点进行分析的基础上,提出了一种基于改进迭代决策树算法的目标威胁评估模型。通过实例对比验证了该模型的有效性和正确性。

In order to solve the shortcomings of the current target threat assessment model,the target threat assessment sys-tem is improved based on the analysis of characteristics of target threat data,the improved gradient boosted decision trees is appliedin target threat assessment model. With a compared example,this paper proves the usefulness and the accuracy of the model.
