Selective Network Discovery via Deep Reinforcement Learning on Embedded Spaces [article]

Peter Morales, Rajmonda Sulo Caceres, Tina Eliassi-Rad
2020 arXiv   pre-print
We propose a framework, called Network Actor Critic (NAC), which learns a policy and notion of future reward in an offline setting via a deep reinforcement learning algorithm.  ...  Complex networks are often either too large for full exploration, partially accessible, or partially observed. Downstream learning tasks on these incomplete networks can produce low quality results.  ...  Reinforcement learning for tasks on complex networks is a relatively new perspective.  ...
