Data augmentation is a popular technique which helps improve generalization capabilities of deep neural net- works, and can be perceived as implicit regularization. It is widely adopted in scenarios where acquiring high- quality training data is time-consuming and costly, with hyperspectral satellite imaging (HSI) being a real-life example. In this paper, we investigate data augmentation policies (exploiting various techniques, including generative adversarial networks applied to elaborate artificial HSI data) which help improve the generalization of deep neural networks (and other supervised learners) by increasing the representativeness of training sets. Our experimental study performed over HSI benchmarks showed that hyperspectral data augmentation boosts the classification accuracy of the models without sacrificing their real-time inference speed.
