VerifiedSparse rewards are one of the most challenging problems in reinforcement learning, where an agent only receives a reward upon completing a specific objective.76% similarUnverifiedThe common bottleneck of existing causal reinforcement learning methods is the acquisition of causal structure, which either needs to be learned from data (error-prone) or manually specified by experts (costly).74% similarUnverifiedRelying solely on latent distance to guide action selection is insufficient, and new representation learning objectives or planning algorithms need to be explored.72% similarUnverifiedThe core challenge faced by reinforcement learning in robotics is extremely low sample efficiency—having a real robot perform millions of trial-and-error attempts is time-consuming and risks hardware wear—which has driven sim-to-real transfer and offline reinforcement learning to become research hotspots.71% similar
