Abstract: In this talk we discuss the different demand forecasts we need to generate to optimize the interventions we make in the three-sided marketplace of on-demand food delivery. We go through different data preparation and modeling techniques for different prediction horizons and granularity. Further, we discuss some of the downstream secondary models which consume these forecasts to make optimal business decisions. Lastly we touch on how the Data Science team is organized at DoorDash to best execute on these problems.
