What you need to know about data augmentation for machine learning

Plentiful high-quality data is the key to great machine learning models. But good data doesn't grow on trees, and that scarcity can impede the development of a model. One way to get around a lack of data is to augment your dataset. Smart approaches to programmatic data augmentation can increase the size of your training set 10-fold or more. Even better, your model will often be more robust (and prevent overfitting) and can even be simpler due to a better training set.
