Harnessing Organizational Knowledge for Machine Learning
One of the biggest bottlenecks in developing machine learning (ML) applications is the need for the large, labeled datasets used to train modern ML models. Creating these datasets involves the investment of significant time and expense, requiring annotators with the right expertise. Moreover, due to the evolution of real-world applications, labeled datasets often need to be thrown out or re-labeled. In collaboration with Stanford and Brown University, we present "Snorkel Drybell: A Case Study in Deploying Weak Supervision at Industrial Scale," which explores how existing knowledge in an organization can be used as noisier, higher-level supervision—or, as it is often termed, weak supervision—to quickly label large training datasets. In this study, we use an experimental internal system, Snorkel Drybell, which adapts the open-source Snorkel framework to use diverse organizational knowledge resources—like internal models, ontologies, legacy rules, knowledge graphs and more—in...
