In deep reinforcement learning, a pruned network is a good network

Recent work has shown that deep reinforcement learning agents have difficulty
in effectively using their network parameters. We leverage prior insights into
the advantages of sparse training techniques and demonstrate that gradual
magnitude pruning enables agents to maximize parameter effectiveness. This
results in networks that yield dramatic performance improvements over
traditional networks and exhibit a type of "scaling law", using only a small
fraction of the full network parameters.
