Domain Randomization and Generative Models for Robotic Grasping

Joshua Tobin, Lukas Biewald, Rocky Duan +8

Deep learning-based robotic grasping has made significant progress thanks to algorithmic improvements and increased data availability. However, state-of-the-art models are often tr…

Hindsight Experience Replay

Marcin Andrychowicz, Filip Wolski, Alex Ray +7

Dealing with sparse rewards is one of the biggest challenges in Reinforcement Learning (RL). We present a novel technique called Hindsight Experience Replay which allows sample-eff…
