Trust Region Policy Optimization 接下来,我们介绍TRPO这篇文章。这篇论文主要研究了一种如何让你的policy在累计reward上一定能够得到提升的方法,要研究这个东西我们首先需要搞清楚一个问题,那就是,两个不同的polocy他们的效果的区别在哪里?只有找到两者的联系,我们才能设计一种更好的更新策略。 首先,这里我们研究的是...

这篇博文是John S., Sergey L., Pieter A., Michael J., Philipp M.,Trust Region Policy Optimization. Proceedings of the 32nd International Conference on Machine Learning, PMLR 37:1889-1897, 2015.的阅读笔记,用来介绍TRPO策略优化方法及其一些公式的推导。TRPO是一种基于策略梯度的强化学习方法,除了定理...
PPO,Proximal Policy Optimization Algorithms 论文阅读 policy使得policy调整在阈值内的那些数据的结果。 上面目标函数的目的就是让policy的更新不会与之前差别太大,类似TRPO的trustregion。在spinningup中将上式进行了一点...TRPO的优化方式比较复杂,对于某些模型结构无法使用,例如模型使用了dropout或policy跟value function模...
Trust Region Policy Optimization (TRPO) 算法是一个 model-free、policy-based、on-policy、Mento Carlo 的算法,且支持连续的状态空间和连续的动作空间,也支持高维输入、神经网络作为函数approximator。 主要的特点 最小化某个替代的损失函数以保证策略能够被单调地改进 ...
Trust region policy optimization (TRPO) is an on-policy, policy gradient reinforcement learning method for environments with a discrete or continuous action space. It directly estimates a stochastic policy and uses a value function critic to estimate the value of the policy. The KL-divergence betwee...
Trust region policy optimization (TRPO) is a popular and empirically successful policy search algorithm in Reinforcement Learning (RL) in which a surrogate problem, that restricts consecutive policies to be 'close' to one another, is ite... L Shani,Y Efroni,S Mannor - Aaai Conference on Artif...
