"Machine Learning in an Exchange Environment"

Abstract: Machine learning involves very large regressions, with as many as a billion explanatory variables. Due to the scale, point estimates are typically used, so that common economic concepts like standard errors are ignored. The talk focuses on applications of ML in an exchange environment, as arises in internet advertising. The use of ML in an auction suggests several ways of improving ML: dealing with the winner's curse, accommodating the inevitable prediction errors into pricing, and choosing a loss function appropriate to the application. In addition, it is shown that active learning strategies have modest payoffs.
