Subject Re: Metron-265 Model as a Service
Date Mon, 04 Jul 2016 20:49:02 GMT
I left a comment on the JIRA.  I think your design is promising.  One other thing I would suggest
is for us to crowd source requirements around model management.  Specifically: 

Model versioning and retention
Model access controls management
Requirements around concept drift 
Requirements around model output
Any model audit and logging requirements 
What model metrics need to be exposed 
Requirements around failure modes
