Difference between Cumulocity IoT ML and Zementis?

Cumulocity IoT’s machine learning capabilities are powered by Zementis behind the scenes.

Machine Learning Workbench is a new tool that allows you to build and train models directly using Cumulocity IoT (whereas Zementis is predominantly an execution environment for pre-built models).
