Deep learning has revolutionized the performance of classification, but in many settings where either massively annotating labels is a labor-intensive task, or only limited datasets are available, a deep learning model will easily overfit and generalizes poorly. Data augmentation as a problem of training a class-conditional and supervised generative adversarial network (GAN) is elaborately formulated in a deep adversarial data augmentation (DADA) technique. Simulation were carried out on CIFAR-100, CIFAR-10 and SVNH to train deep classifiers in the extremely low data regimes showing improved performance through DADA over traditional data augmentation. Deep classifiers were trained on three real-world small datasets: the Karolinska Directed Emotional Faces (KDEF) dataset for the facial expression recognition task, a Brain-Computer Interface (BCI) Competition dataset for the EEG brain signal classification task, and the Curated Breast Imaging Subset of the Digital Database for Screening Mammography (CBIS-DDSM) dataset for the tumor classification task. For all of them, DADA leads to highly competitive generalization performance.
