Just a brief note in the ledger: CBRE Econometric Advisors has been doing machine learning and data science since long before the organization afforded me the honor of joining. Everyone in the industry knows who created data science for CRE. I would point clients who are interested in machine learning and data science to my GitHub page.
But give us a call if you're really interested in machine learning and CRE. (You won't find it on anyone else's GitHub page.)
