On-Robot Bayesian Reinforcement Learning for POMDPs

no code implementations22 Jul 2023 Hai Nguyen, Sammie Katt, Yuchen Xiao, Christopher Amato

Bayesian reinforcement learning (BRL), thanks to its sample efficiency and ability to exploit prior knowledge, is uniquely positioned as such a solution method.

BADDr: Bayes-Adaptive Deep Dropout RL for POMDPs

no code implementations17 Feb 2022 Sammie Katt, Hai Nguyen, Frans A. Oliehoek, Christopher Amato

Under this parameterization, in contrast to previous work, the belief over the state and dynamics is a more scalable inference problem.

Removing Dynamic Objects for Static Scene Reconstruction using Light Fields

no code implementations24 Mar 2020 Pushyami Kaveti, Sammie Katt, Hanumant Singh

In this paper we present a method to synthesize a refocused image of the static background in the presence of dynamic objects that uses a light-field acquired with a linear camera array.

Learning in POMDPs with Monte Carlo Tree Search

no code implementations ICML 2017 Sammie Katt, Frans A. Oliehoek, Christopher Amato

The POMDP is a powerful framework for reasoning under outcome and information uncertainty, but constructing an accurate POMDP model is difficult.
