Sure! Techniques include synonym replacement, back-translation, and random insertion of words.

How does data augmentation affect model accuracy?

It generally enhances model accuracy by providing more varied examples, allowing the model to generalize better.

Are there any downsides to using data augmentation?

Yes, if not done carefully, it can introduce noise or irrelevant data, potentially harming model performance.

What types of NLP tasks benefit the most from data augmentation?

Tasks like text classification, sentiment analysis, and named entity recognition often see significant improvements.
