摘要

航班延误是许多航空旅客面临的常见问题之一。航班延误不仅给乘客带来不便,而且给航空公司带来了巨大的损失。为了简化旅行体验,航空公司一直在利用数据分析来预测航班延误。尽管已经提出了许多预测模型,但它们在类分布不平衡的数据上表现不佳。通常,这些模型不太关注少数“延迟”类,而这类通常更相关、更重要。在本文中,我们解决了类分布不平衡的问题,以提高预测航班延误的整体分类性能。我们在一个公共航空公司的准点率数据集上验证了我们的方法。

Modelling Flight Delays in the Presence of Class Imbalance
Flight delay is one of the common problems faced by many air passengers. Delays in flights not only bring about inconvenience to passengers, but also cost the airlines. To streamline travel experience, airlines have been leveraging on data analytics to predict flight delays. Although many prediction models have been proposed, they perform poorly especially on data that have imbalanced class distributions. Often, these models pay less attention to the minority 'delay' class, which are usually more relevant and important. In this paper, we address the issue of imbalanced class distributions to improve the overall classification performance in predicting flight delays. We validated our approach on a public airline on-time performance dataset.
