Deep learning in remote sensing scene classification: a data augmentation enhanced convolutional neural network framework

Abstract: The recent emergence of deep learning for characterizing complex patterns in remote sensing imagery reveals its high potential to address some classic challenges in this domain, e.g. scene classification. Typical deep learning models require extremely large datasets with rich contents to train a multi-layer structure in order to capture the essential features of scenes. Compared with the benchmark datasets used in popular deep learning frameworks, however, the volumes of available remote sensing datasets are p… Show more

“…Given the unbalanced sampling among the three semantic classes, we incorporated sample weighting, with weights calculated as the inverse frequency of each class, to enhance the robustness of our model. To improve the accuracy of the network, we also augmented the training data by randomly shifting, rotating and reflecting it to create multiple versions of the data [45,46]. With a fully specified model, we trained it using mini-batch stochastic gradient descent with momentum (SGDM) as the optimizer with 75% of the labeled data and 15% of the data for validation.…”

“…However, data labeled as center pivot systems were much less than data labeled as non-center pivot systems. To overcome the limited number of samples, image transformations, such as flipping, rotating, and cropping have been proposed [44,45]. In this work, a sampling approach was proposed to augment the number of training samples.…”

“…The stacked autoencoder is an unsupervised learning model, which trains an one-hidden layer neural network to reconstruct input data from the latent representation [13]. In recent years, neural network models [14] show a great potentials in learning hidden representations. Given a set of data instances…”
