二、Model-Based RL 的基本思想 MBRL 算法的核心思想是,通过学习环境的动态模型和奖励函数,利用这些模型进行规划和决策,从而提高样本效率。与 Model-Free RL 直接学习策略或价值函数不同,MBRL 首先学习环境的内在模型,然后利用这个模型来指导策略的学习和执行。 这里的核心在于「环境模型」,指的是环境的动态模型和奖...
在强化学习的研究中，基于模型的强化学习（Model-Based RL）和无模型强化学习（Model-Free RL）是两个...
在学习强化学习的过程中,有两个名词早晚会出现在我们面前,就是Model-Based和Model-Free。在一些资料中,我们经常会见到“这是一个Model-Based 的算法”或者“这个方法是典型的Model-Free的算法”的说法。“Model-Based”通常被翻译成“基于模型”,“Model-Free”通常被翻译成“无模型”。可能有人会问:为什么会有这...
对于大脑中同时存在基于多巴胺引起的突触可塑性、基于PFC电活动的两套强化学习系统的解释,一种观点认为大脑中同时存在两套强化学习系统——负责model-freeRL的多巴胺系统和负责model-basedRL的PFC系统(Daw et al., 2005)。尽管在深度学习中的强化学习领域,model-...
Reinforcement learning (RL) techniques are a set of solutions for optimal long-term action choice such that actions take into account both immediate and delayed consequences. They fall into two broad classes. Model-based approaches assume an explicit model of theQJM Huys...

4. Model-based RL In a way, we could argue that Q-learning is model-based. After all, we’re building a Q-table, which can be seen as a model of the environment. However, this isn’t how the termmodel-basedis used in the field. ...
作者把这个方法叫做TD-k trick。有了这个之后,就用来训model free RL就行了。作者用的是DDPG,整个算法如下 总结:这篇文章提出的MVE算是很多model based算法的起点了,在这个方向上挺出名的了。另外这个H不太好确定,所以后面就出现了一些工作来自适应选择H。

They fall into two broad classes. Model-based approaches assume an explicit model of the environment and the agent. The mod...
