In this paper, researchers develop an algorithm for reinforcement learning with sparse rewards using deep deterministic policy gradients (DDPG). To improve exploration, they introduce a search procedure called {}{t}-greedy that generates options for visiting less-explored states. The team also proposes a dual experience replay buffer framework, GDRB, and implements longest n-step returns to efficiently use rewarded transitions. The resulting algorithm, ETGL-DDPG, integrates these techniques into DDPG and outperforms other state-of-the-art methods on standard benchmarks in continuous environments with sparse rewards.

This paper explores ways to improve deep learning algorithms for tasks that have sparse rewards. In other words, it’s about finding the best way to learn from rewards when those rewards are only given sometimes. To do this, the authors create a new algorithm called ETGL-DDPG that combines different techniques to help the algorithm explore and learn more efficiently.
