Webpolicy_update_delay – Delay of policy updates. Policy is updated once in policy_update_delay times of Q-function updates. target_policy_smoothing_func (callable) – Callable that takes a batch of actions as input and outputs a noisy version of it. It is used for target policy smoothing when computing target Q-values. Webtarget policy smoothing实质上是算法的正则化器。 它解决了DDPG中可能发生的特定故障:如果Q函数逼近器为某些操作产生了不正确的尖峰,该策略将迅速利用该峰,并出现脆性或错误行为。 可以通过在类似action上使Q函数变得平滑来修正,即target policy smoothing。 WebSep 7, 2024 · In this section, we first propose an improved exploration strategy and then a modified version of the target policy smoothing technique in TD3. Next, we discuss utility of a set of recent deep learning techniques that have not been commonly used in deep RL. 4.1 Exploration over Bounded Action Spaces ccew serial number
