<dcterms:abstract>As data quality and quantity increase, the prediction of future events using machine learning&#xd;
(ML) techniques across engineering disciplines grows by the day. Air transportation cannot&#xd;
be an exception. Delay prediction is paramount in the aerospace industry, since air traffic&#xd;
delays are responsible for millions of dollars in losses to airlines and passengers, along with&#xd;
negative impacts on the environment. In this contribution, we leverage recent signal&#xd;
processing and ML advances to put forth a processing-and-learning pipeline for the&#xd;
prediction of air traffic delays. The proposed approach is executed in several steps. Firstly,&#xd;
we apply signal processing and data science techniques to filter and denoise the original&#xd;
information. Secondly, we run a descriptive analysis of the data and design new features&#xd;
tailored to the prediction problem. Thirdly, we implement a scheme to select the most&#xd;
informative of those features, contributing to a better generalization performance, and&#xd;
offering useful insights. Two algorithms are used to that end: one based on random forests&#xd;
and one employing a sparse logistic regression approach. Finally, once the features are&#xd;
selected, we implement, analyse, and compare several ML architectures (from classical&#xd;
classifiers to deep learning) to predict the delay. While the focus of the comparison is&#xd;
prediction accuracy, metrics such as sample and computational complexity are also&#xd;
discussed. Numerical experiments are drawn from the US domestic market for the year 2018,&#xd;
when more than 7 million flights between 358 airports were flown. The designed&#xd;
processing/learning pipeline reveals interesting insights and achieves better prediction&#xd;
results than the state of the art. The results confirm that air traffic delay prediction is a&#xd;
challenging problem, mainly because the delay is extremely airport-dependent and the data&#xd;
is highly unbalanced (i.e., only a small percentage of flights are noticeable delayed), and&#xd;
identify worth-pursuing future lines of work.</dcterms:abstract>
