ETGL-DDPG: A Deep Deterministic Policy Gradient Algorithm for Sparse Reward Continuous Control

Ehsan Futuhi, Shayan Karimi, Chao Gao +1

We consider deep deterministic policy gradient (DDPG) in the context of reinforcement learning with sparse rewards. To enhance exploration, we introduce a search procedure, \emph{$…

Computational Hardness of Reinforcement Learning with Partial $q^{I ¨} $ -Realizability

Shayan Karimi, Xiaoqi Tan

This paper investigates the computational complexity of reinforcement learning in a novel linear function approximation regime, termed partial $q^{I ¨} $ -realizability. In this framewo…
