摘要：The rapid growth of air traffic has continuously increased the workload of controllers,which has become an important factor restricting sector *** similar traffic scenes can be identified,the historical decision-making experience may be used to help controllers decide control strategies *** that there are many traffic scenes and it is hard to label them all,in this paper,we propose an active SVM metric learning(ASVM2L)algorithm to measure and identify the similar traffic *** of all,we obtain some traffic scene samples correctly labeled by experienced air traffic *** design an active sampling strategy based on voting difference to choose the most valuable unlabeled samples and label *** the metric matrix of all the labeled samples is learned and used to complete the classification of traffic *** verify the effectiveness of ASVM2L on standard data sets,and then use it to measure and classify the traffic scenes on the historical air traffic data set of the Central South Sector of *** experimental results show that,compared with other existing methods,the proposed method can use the information of traffic scene samples more thoroughly and achieve better classification performance under limited labeled samples.
