摘要
模型选择是模型管理的重要部分．本文提出利用二元决策树实现模型选择，并采用遗传算法构造二元决策树．最后给出了在趋势预测模型选择中的应用实例。
Model selection plays an important role in model management. Genetic algorithm is employed to construct binary decision tree which is used to select model in this paper. The application sample for trend forecast model selection is given and the factors that influence the inaccurate ration of binary decision tree is discussed.
