Easy Data Augmentation Techniques for Text Classification

This video explains a great baseline for exploring data augmentation in NLP and text classification particularly. Synonym replacement, random insertion/deletion/swapping can all be quickly implemented and don't require much overhead (compared to say back-translation or generative modeling).
