ML project lifecycle <-> Proof of Concept

Hi all, Thank you very much for sharing the ML project lifecycle.

I am wondering how the idea of Proof of Concept fit into it.

Is the POC the outcome of the modeling phase?

Hi Jan and welcome to our community!
The primary goal of a POC is just to decide if the application is workable and worth building and deploiyng. Prof.Andrew Ng advices most teams during the POC to focus on getting the prototype to work even if some preprocessing stuff are done manually during this phase.
Hope this can help
