简述:on-policy算法需要很多sample,off-policy不能保证收敛,尤其是continuous环境中。为了解决这些问题,上帝说要有an off-policy actor-critic RL algorithm based on the maximum entropy RL framework,于是就有了SAC。SAC使用了maximum entropy reinforcement learning,即最大化熵强化学习,使得policy更倾向于探索,并且在...

Sarsa(\lambda)引入ET概念可以更有效的在线学习,因为不必要学习完整的回合,数据用完即可丢弃。ET通常较多地应用于在线学习算法中(online algorithm)。 Sarsa(\lambda)的算法实现如下: Image 注:E(s,a)在每访问完一个回合后需要重新置0,这体现了ET仅在一个Episode中发挥作用;其次,算法更新Q和E的时候针对的不是某...
Here, we present an evaluation of the magnitude of tropospheric artifacts in derived time series after compensation using an algorithm that requires only the InSAR data. The level of artifact reduction equals or exceeds that from many weather model-based methods, while avoiding the need to...
相当于用model来做short-term horizon的估计,用Q-learning来做long-term的估计(We present model-based value expansion (MVE), a hybrid algorithm that uses a dynamics model to simulate the short-term horizon and Q-learning to estimate the long-term value beyond the simulation horizon.)。

To advance understanding of the ceiling temperature characters in tunnel fires, a physical model-free ant colony optimization network algorithm is ...
Algorithm 1 描述了the model-free episodic control的基本过程。算法分成两步,第一步根据表里面的策略执行动作,完成一个完整的episode,记录每一步的奖赏。最关键的要把观察到的状态值映射成S。第二步就是通过后向演算来更新改进表里面的策略。有意思的是,这种后向更新可能是海马体的算法,但是到目前为止,我们还不...
The proposed strategy is based on replacing the PI current controllers in the inner loop with the proposed predictive control algorithm, while, in the outer loop, a classical PI controller is used to control the mechanical speed of the rotor. But there are also IM control structures that keep...

A model-free predictive control algorithm based on linearization of partial format is proposed for a class of nonlinear systems which are described by NARMAX model. In the algorithm, linearization of partial format is used to convert nonlinear systems which are described by NARMAX model into linear...
