KL penalty和Clip PPO算法的核心在于更新策略梯度,主流方法有两种,分别是KL散度做penalty,另一种是Clip剪裁,它们的主要作用都是限制策略梯度更新的幅度,从而推导出不同的神经网络参数更新方式 采用KL penalty算法,那么神经网络参数按照下面的方式更新 采用Clip算法,那么神经网络参数按照下面的方式更新 那么采用KL penalty算...
PPO（Proximal Policy Optimization）是基于策略的强化学习算法，属于off-policy算法。核心在于通过KL散度或Clip方法限制策略梯度更新的幅度，从而优化策略。使用KL penalty算法时，神经网络参数按特定公式更新；采用Clip算法时，参数更新方式亦有差异。这两种方法在PPO算法中体现为更新策略的不同方式。伪代码展示...
在KL penalty一直作用的前提下，这个噪声项应该是相对可控的。
