WebJul 10, 2024 · Sometimes, it can be helpful to distinguish a single species, like prairie dogs, from the overall family to which they belong.In this case, prairie dogs are one of many types of ground squirrels. In this article, we’re going to parse the subject of a ground squirrel vs prairie dog and show you how they’re different from one another. WebThen, recently, I changed my DQN algorithm and turned it into a DDPG/D4PG algorithm. I used the same noisy network algorithm for exploration and it still gave me fine agents from time to time. However, it often did not perform significantly better than the ones that used action space noise with the Ornstein-Uhlenbeck process, sometimes ...

WebNo projection is required, instead, Wasserstein distance (quantile Huber loss) gives finer comparison between return distributions. Once the model is trained, the value distribution can be recovered easily to arbitrary precision by sampling.
