What is Snorkel?

Snorkel is a data-centric AI platform that uses programmatic data labeling (also known as weak supervision) to accelerate the development of AI applications. Instead of manually labeling large datasets, developers define labeling functions based on domain expertise, heuristics, or patterns. These functions automatically generate labels, which are then used to train machine learning models. Snorkel is particularly useful when labeled data is scarce or expensive to obtain, and it helps to improve model accuracy and reduce development time.
