AutoML from Service Provider's Perspective: Multi-device, Multi-tenant Model Selection with GP-EI

no code implementations17 Mar 2018 Chen Yu, Bojan Karlas, Jie Zhong, Ce Zhang, Ji Liu

In this paper, we focus on the AutoML problem from the \emph{service provider's perspective}, motivated by the following practical consideration: When an AutoML service needs to serve {\em multiple users} with {\em multiple devices} at the same time, how can we allocate these devices to users in an efficient way?
