Data Quality
"Quality or quantity, Don't tell me they're the same"
- Song by Bad Religion
What is data Quality?
Maintaining the quality of data flowing into a model can be challenging due to upstream data changes and the increasing pace of data proliferation as organizations scale.
Why monitor data quality?
Data quality monitors enable teams to quickly catch when features, predictions, or actuals data don't conform with what is expected.
Pre-configured data quality monitoring policies
