理解Advantage Actor-Critic算法 熟悉Python 一定程度了解PyTorch 安装了OpenAI Gym的环境 3 Advantage Actor-Critic 算法简介 这里直接引用David Silver的Talk课件。 我们要构造两个网络:Actor Network和Value Network 其中Actor Network的更新使用Policy Gradient,而Value Network的更新使用MSELoss。 关于Policy Gradient方法不...
一句话概括 A3C:Google DeepMind 提出的一种解决Actor-Critic不收敛问题的算法. 它会创建多个并行的环境, 让多个拥有副结构的 agent 同时在这些并行环境上更新主结构中的参数. 并行中的 agent 们互不干扰, 而主结构的参数更新受到副结构提交更新的不连续性干扰, 所以更新的相关性被降低, 收敛性提高. 因为这节内...

This is a story about the Actor Advantage Critic (A2C) model. Actor-Critic models are a popular form of Policy Gradient model, which is itself a vanilla RL algorithm. If you understand the A2C, you understand deep RL. After you’ve gained an intuition for the A2C, check out: ...
exp_name- string of the name of the experiment. Determines the name that the PyTorch state dicts are saved to. model_type- Denotes the model architecture to be used in training. Options include 'fc', 'conv', 'a3c', 'gru' env_type- string of the type of environment you would like ...

PyTorch implementation of Asynchronous Advantage Actor Critic (A3C) from "Asynchronous Methods for Deep Reinforcement Learning". - ikostrikov/pytorch-a3c
This is a PyTorch implementation of Asynchronous Advantage Actor Critic (A3C) from"Asynchronous Methods for Deep Reinforcement Learning". This implementation is inspired byUniverse Starter Agent. In contrast to the starter agent, it uses an optimizer with shared statistics as in the original paper. ...
pytorch-a2c-ppo-acktr Please use hyper parameters from this readme. With other hyper parameters things might not work (it's RL after all)! This is a PyTorch implementation of Advantage Actor Critic (A2C), a synchronous deterministic version ofA3C ...
