Submodular Secretary Problem with Shortlists
Shipra Agrawal, Mohammad Shadravan, Cliff Stein
In submodular -secretary problem, the goal is to select items in a randomly ordered input so as to maximize the expected value of a given monotone submodular function on the…
Boosting Trust Region Policy Optimization by Normalizing Flows Policy
Yunhao Tang, Shipra Agrawal
We propose to improve trust region policy search with normalizing flows policy. We illustrate that when the trust region is constructed by KL divergence constraints, normalizing fl…
Exploration by Distributional Reinforcement Learning
Yunhao Tang, Shipra Agrawal
We propose a framework based on distributional reinforcement learning and recent attempts to combine Bayesian parameter updates with deep reinforcement learning. We show that our p…
Implicit Policy for Reinforcement Learning
Yunhao Tang, Shipra Agrawal
We introduce Implicit Policy, a general class of expressive policies that can flexibly represent complex action distributions in reinforcement learning, with efficient algorithms t…
Robust Repeated Auctions under Heterogeneous Buyer Behavior
Shipra Agrawal, Constantinos Daskalakis, Vahab Mirrokni +1
We study revenue optimization in a repeated auction between a single seller and a single buyer. Traditionally, the design of repeated auctions requires strong modeling assumptions…
