Data & Analytics

4.3 / 5.0

Snorkel AI is a programmatic data labeling platform that uses weak supervision - allowing ML teams to label training data using heuristic labeling functions instead of manual annotation. Its Snorkel Flow platform enables domain experts to write labeling rules that programmatically generate training labels, reducing annotation costs by 10-100x. Used by Google, Intel, and government agencies.

Best for: Enterprise ML teams needing to label large datasets cost-practically using programmatic weak supervision instead of manual annotation
