Abstract

In China's civil aviation transportation industry, flight safety has been the focus of attention. In this paper, a flight technology assessment model and an automated early warning model are established for aviation safety. First, data pre-processing is performed. Then the suitable indicators are continuously screened by multiple machine learning classifications, and then the screened data are fitted to continuously screen the suitable indicators, and the aircraft technology assessment is found to be more suitable for the integrated learning classification model. Subsequently, three unoptimized optimal models were derived as LightGBM, XGboost and Random Forest classification models. The results of these models are then fused by Stacking model to combine their advantages to build the final aircraft technology assessment prediction model. For the automated early warning mechanism, the aviation early warning mechanism needs to be established first by subclassing these data with the K-mean clustering model and visualizing the key data items such as avg (COG NORM ACCEL) based on the normal distribution, combined with the differentiated distribution for each category to set the implausible warning level to establish the aviation automated early warning model.
基于机器学习算法的飞行技术评估研究
在中国民航运输业,飞行安全一直是人们关注的焦点。本文建立了航空安全飞行技术评估模型和自动预警模型。首先,进行数据预处理。然后通过多个机器学习分类连续筛选合适的指标,然后对筛选的数据进行拟合,连续筛选合适的指标,发现飞机技术评估更适合综合学习分类模型。随后,导出了三个未优化的最优模型,分别是LightGBM、XGboost和Random Forest分类模型。然后用Stacking模型对各模型的结果进行融合,结合各模型的优点,建立最终飞机技术评估预测模型。对于自动化预警机制,首先需要建立航空预警机制,将这些数据用k -均值聚类模型进行子类化,并根据正态分布对avg (COG NORM ACCEL)等关键数据项进行可视化,结合各类别的差异化分布设置不合理预警等级,建立航空自动化预警模型。
