How to effectively make use of a GPU for reinforcement learning? : <p>Recently i looked into reinforcement learning and there was one question bugging me, that i could not find an answer for: How is training effectively done using GPUs? To my understanding constant interaction with an environment is required, which for me seems like a huge bottleneck, since this task is often non-mathematical / non-parallelizable. Yet for example Alpha Go uses multiple TPUs/GPUs. So how are they doing it?</p>
