In this workshop we plan to focus on the problems more than on solutions. We will consider problems such as identifying dysfunctional items or collections in a website, off-policy evaluation of marketing strategies, personalization of e-commerce experience, validation, sequential decisions, dynamic pricing, and others. Our main goal is to portray the main challenges of the field and to propose an industry-academia agreed collection of benchmarks problems for theoretical study and experimental work.
