一句话概括 DDPG: Google DeepMind 提出的一种使用 Actor Critic 结构, 但是输出的不是行为的概率, 而是具体的行为, 用于连续动作 (continuous action) 的预测. DDPG 结合了之前获得成功的 DQN 结构, 提高了 Actor Critic 的稳定性和收敛性. 因为 DDPG 和 DQN

PyTorch 的开发/使用团队包括 Facebook, NVIDIA, Twitter 等, 都是大品牌, 算得上是 Tensorflow 的一大竞争对手. PyTorch 使用起来简单明快, 它和 Tensorflow 等静态图计算的模块相比, 最大的优势就是, 它的计算方式都是动态的, 这样的形式在 RNN 等模式中有着明显

零基础入门机器学习不是一件困难的事. 机器学习或者深度学习本来可以很简单, 很多时候我们不必要花特别多的经历在复杂的数学上. 数学只是一种达成目的的工具, 很多时候我们只要知道这个工具怎么用就好了, 后面的原理多多少少的有些了解就能非常

DDPG trains a deterministic policy in an off-policy way. Because the policy is deterministic, if the agent were to explore on-policy, in the beginning it would probably not try a wide enough variety of actions to find useful learning signals. To make DDPG policies
