A Markov Decision Process Analysis of the Cold Start Problem in Bayesian Information Filtering
Xiaoting Zhao, Peter I. Frazier
We consider the information filtering problem, in which we face a stream of items, and must decide which ones to forward to a user to maximize the number of relevant items shown, m…
A New Optimal Stepsize For Approximate Dynamic Programming
Ilya O. Ryzhov, Peter I. Frazier, Warren B. Powell
Approximate dynamic programming (ADP) has proven itself in a wide range of applications spanning large-scale transportation problems, health care, revenue management, and energy sy…
Exploration vs. Exploitation in the Information Filtering Problem
Xiaoting Zhao, Peter I. Frazier
We consider information filtering, in which we face a stream of items too voluminous to process by hand (e.g., scientific articles, blog posts, emails), and must rely on a computer…
Probabilistic Group Testing under Sum Observations: A Parallelizable 2-Approximation for Entropy Loss
Weidong Han, Purnima Rajan, Peter I. Frazier +1
We consider the problem of group testing with sum observations and noiseless answers, in which we aim to locate multiple objects by querying the number of objects in each of a sequ…
