bigiceberg M 基于熵的强化学习框架2017年由Berkeley和Google的一些研究员重新定义,目前它的理论基础已逐渐完善,在机器臂操控、人运动模拟等连续动作空间的RL任务中有较大应用潜力。本文对其基本思路做一个简述。 一、基本符号及定义 基本符号:一个MDP由 (S,A,p,r,\gamma) 组成,S和A分别为连续的状态空间和动作...
Episodic tasks come to an end whenever the agent reaches aterminal state. The Reward Hypothesis Reward Hypothesis: All goals can be framed as the maximization of (expected) cumulative reward. (奖励假设又被称为强化学习假设,这个假设如果不成立,强化学习的根基就会动摇,这里是Sutton和他学生关于这个假设的...
可以把actor想成是GAN里的Generator, 把reward function想成是Discriminator。 IRL framework1 IRL framework2 IRL常用来训练机械手臂 用IRL之前教机器一个简单的动作也需要很多的代码很费力气。 IRL之前的机械手臂 用了IRL以后: IRL之后的机械手臂 To Learn More…… 还有一个更潮的做法是给机器一个画面让机器做到...

PokerRL Framework Components of a PokerRL Algorithm Your algorithm consists of workers (green) that interact with each other. Arguments for a training run are passed through an instance of aTrainingProfile(.../rl/base_cls/TrainingProfileBase). Common metrics like best-response or head-to-head ...
Representation learning also provides an elegant conceptual framework for obtaining provably efficient algorithms for complex environments and advancing the theoretical foundations of RL. “We know RL is not statistically tractable in general;...

Here’s how the agent goes through each time step initiated by the RL framework. As explained above, the model will initially predict random actions, but after a few training rounds, it’ll get much smarter. defstep(self,action):# First, react to the actions and adjust the fleetturn_on...
