In this talk, I will talk about several of my experiences of technology transfer over the past 10 years at Microsoft, Facebook and Amazon. Technology transfer - the process of moving promising research topics into a level of maturity that's ready for bulk manufacturing or production - remains one of the largest mysteries and unsolved social and organizational problems. There are some surprising similarities in the various technology transfers of mathematical models and algorithms into products and I will attempt to group and discuss them. During the course of the talk, I will introduce graphical models and approximate message passing as well as their application to gamer ranking and computational online advertising.
