Deep Reinforcement Learning for Adaptive Exploration of Unknown Environments

1 code implementation4 May 2021 Ashley Peake, Joe McCalmon, Yixin Zhang, Daniel Myers, Sarra Alqahtani, Paul Pauca

Often, these missions start with building a map for the environment via pure exploration and subsequently using (i. e. exploiting) the generated map for downstream navigation tasks.
