自动飞行员复诵指令生成方法研究

Automatic Pilot s Recitation Instruction Generation Method

为了提高效率,降低培训成本并推广使用计算机来取代管制模拟机中的飞行员席位,采用集成学习的策略来生成飞行员复诵指令。选用5个大规模预训练语言模型进行微调,并使用K折交叉验证来筛选出性能较好的4个模型作为基础模型来构建集成学习模型。所构建的集成学习模型在管制指令数据集上取得在本领域中的最优效果。在通用的ROUGE(recall-oriented understudy for gisting evaluation)评价标准中,取得R_(OUGE-1)=0.998,R_(OUGE-2)=0.995,R_(OUGE-L)=0.998的最新效果。其中,R_(OUGE-1)关注参考文本与生成文本之间单个单词的匹配度,R_(OUGE-2)则关注两个连续单词的匹配度,R_(OUGE-L)则关注最长公共子序列的匹配度。为了克服通用指标在本领域的局限性,更准确地评估模型性能,针对生成的复诵指令提出一套基于关键词的评价标准。该评价指标准基于管制文本分词后的结果计算各个关键词指标来评估模型的效果。在基于关键词的评价标准下,所构建模型取得整体准确率为0.987的最优效果,对航空器呼号的复诵准确率达到0.998。

In order to improve efficiency,reduce training costs,and promote the use of computers to replace the pilot seat in control simulation machines,an ensemble learning strategy was used to generate pilot response instructions.Five large-scale pre-trained language models were selected for fine-tuning,and four models with good performance were selected as the basic models for building the integrated learning model using K-fold cross-validation.The constructed integrated learning model achieved the best performance in this field on the air traffic control instruction dataset.According to the general recall-oriented understudy for gisting evaluation(ROUGE)evaluation criteria,the latest effects of R_(OUGE-1)=0.998,R_(OUGE-2)=0.995,R_(OUGE-L)=0.998 are obtained.R_(OUGE-1) focuses on the matching of individual words between the reference text and the generated text.R_(OUGE-2) concentrates on the matching of two consecutive words,while R_(OUGE-L) is concerned with the matching of the longest common subsequence.In order to overcome the limitations of the general indicators in this field and more accurately evaluate the performance of the model,a set of keyword-based evaluation criteria for generated response instructions was proposed.This evaluation standard calculated various keyword indicators based on the results of segmentation of control texts to evaluate the effect of the model.Under the keyword-based evaluation criteria,the constructed model achieves an overall accuracy of 0.987,with aircraft call sign accuracy of 0.998.
