AWhat changed
Decoupled many diverse-exploration actors from a learner through shared prioritized replay, emphasizing high-throughput experience selection rather than actor-gradient synchronization.
Scientific scope
Decoupled many diverse-exploration actors from a learner through shared prioritized replay, emphasizing high-throughput experience selection rather than actor-gradient synchronization. Combines inherited prioritized replay and off-policy value learning; not their invention or the first distributed RL system. Scale and Atari/control gains are source experiments with hardware and data costs, not universal sample-efficiency or convergence guarantees.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
