Snorkel

Snorkel, from Snorkel AI in Palo Alto, is a system for programmatically building and managing training datasets. In Snorkel, users can develop training datasets rather than hand-labeling them over weeks or months. Snorkel currently exposes three key programmatic operations: labeling data, for example using heuristic rules or distant supervision techniques; transforming data, for example rotating or stretching images to perform data augmentation; and slicing data into different critical subsets. Snorkel then automatically models, cleans, and integrates the resulting training data using novel, theoretically-grounded techniques.
