A Markov Decision Process Analysis of the Cold Start Problem in Bayesian Information Filtering

no code implementations29 Oct 2014 Xiaoting Zhao, Peter I. Frazier

We focus on the cold-start setting for this problem, in which we have limited historical data on the user's preferences, and must rely on feedback from forwarded articles to learn which the fraction of items relevant to the user in each of several item categories.
