Data augmentation is crucial to make machine learning models more robust and safe. However, augmenting data can be challenging as it requires generating diverse data points to rigorously evaluate model behavior on edge cases and mitigate potential harms. Creating high-quality augmentations that cover these “unknown unknowns” is a time- and creativity-intensive task. In this work, we introduce Amplio, an interactive tool to help practitioners navigate “unknown unknowns” in unstructured text datasets and improve data diversity by systematically identifying empty data spaces to explore. Amplio…
