THE PROBLEM

ML evaluation techniques are falling short.

Aggregate metrics don't tell the full story — unexpected model behavior in production is the norm.

Current testing processes are manual, error-prone, and unrepeatable. Models are evaluated on arbitrary statistical metrics that align imperfectly with product objectives.
‍
Tracking model improvement over time as the data evolves is difficult and techniques sufficient in a research environment don't meet the demands of production.

There is a better way.
