摘　　要：在航空领域,飞行学员的飞行技能直接关系到航空安全和运营效率。基于中国民用航空飞行学院某分院飞行学员的训练数据,引入Pearson相关系数,评估特征与目标变量之间的关系强度;根据相关系数确定飞行训练的关键影响因素,建立Pearson相关系数的决策树新模型;通过比较不同阈值和决策树深度,优化新模型在准确率、精确率、召回率和F_(1)分数的性能;在同一数据集上,与随机森林、多层感知机(MLP)、逻辑回归、决策树以及改进后的梯度提升决策树模型的性能进行对比。结果表明:新模型计算结果表现最优,能够为飞行学员的飞行训练提供有效指导,为飞行训练评估提供理论支撑。In the field of aviation,the flight skills of trainee pilots are directly related to aviation safety and opera-tional efficiency.Based on the training data of flight trainees from a branch of Civil Aviation Flight University of China,the Pearson correlation coefficient is introduced to evaluate the strength of the relationship between features and target variable.Based on the correlation coefficients,the key factors influencing flight training are identified,and a novel decision tree model based on Pearson correlation coefficients is established.By optimizing the model with various thresholds and tree depths,its performance in accuracy,precision,recall,and F_(1) score is optimized.The performance of the new model is compared with random forest,multilayer perception(MLP),logistic regres-sion,decision tree and enhanced gradient boosting decision tree model.The results show that the new model is of superior performance,and can provide the effective guidance for flight training,and offer the theoretical support for the evaluation of flight training.
