"synthetic data: partly or completely artificial. Synthetic data are often produced by generative adversarial networks"
"augmented data: derived from real images with some sort of minor and realistic transformation (such as translation, flipping, rotation, or the addition of noise) in order to increase the diversity of the training set"
"Criticisms of the use of augmented, and especially synthetic, data in medical AI include the potential amplification of statistical biases and a general lack of research on their consequences. Nonetheless, data augmentation is used routinely in the development of AI applications for radiology."
