Researchers have analyzed the regularization effects of data augmentation on supervised regression methods, particularly in scenarios where the number of covariates scales with the number of samples. The study provides a precise characterization of test error, using mean squared error, based on population quantities of the true data and statistics of the augmentation process. These findings apply to models with misspecified feature maps and architectures where only the final layer is trained, with the rest of the network being fixed or randomly initialized. AI
IMPACT Provides theoretical insights into data augmentation's impact on regression models, potentially informing future model training strategies.
