one (the best) configuration left. An intuitive way to think about it is to imagine a multiplayer game with multiple levels where a few best performing players are promoted to the next level until we have on the target dataset. The controller model learns to generate better architectures as the search game progresses. Figure 7-4: An overview of Neural Architecture Search framed as a Reinforcement Learning
