The document discusses Zulily's goal of building personalized recommendation systems to provide a tailored shopping experience across platforms by predicting demand, enabling collaborative filtering, and sorting sales based on a member's likelihood to engage. It describes challenges around rapid growth and short sales windows and their approach of breaking products into features and using member interactions to compute interests to recommend relevant sales. It also covers techniques like contextual multi-armed bandits and real-time experimentation to optimize recommendations and landing page images.
