Statistical Learning in Operations: The Interplay between Online and Offline learning.
Traditionally, statistical learning is focused on either (i) online learning where data is generated online according to some unknown model; or (ii) offline learning where the entire data is available at the beginning of the process. In this talk we show that combining both approaches can accelerate learning. First, we show how difficult online learning problems can be reduced to well-understood offline regression problems. Second, we show the impact of pre-existing offline data on online learning and characterize conditions under which offline data helps (does not help) improve online learning. We demonstrate the impact of our work in the context of recommendation systems, multiclass classification problems and dynamic pricing.
