Data augmentation is a statistical technique which allows maximum likelihood estimation from incomplete data.^[1]^[2] Data augmentation has important applications in Bayesian analysis,^[3] and the technique is widely used in machine learning to reduce overfitting when training machine learning models,^[4] achieved by training models on several slightly-modified copies of existing data.
