$\text { 因此 } \nabla \mathrm{p}{\theta}(\tau)=\nabla \log \mathrm{p}{\theta}\left(\mathrm{a}{\mathrm{t}}^{\mathrm{n}} \mid \mathrm{s}{\mathrm{t}}^{\mathrm{n}}\right)$

是不是写错了?

谢谢你的留言,应该是没有写错的,具体的公式推导可见教程 “第四章 策略梯度”。

keywords里的“Reinforce”是不是写成全大写的“REINFORCE”更好些。与之前的笔记更衔接些。

是的是的,这里的REINFORCE表示一种基于策略梯度并使用回合更新的强化学习的经典算法,应该区别于Reinforce,谢谢你的建议,已经改正~

就我觉得符号体系混乱吗?策略一会是p 一会是π,并且和前三章体系也不同,

用 p 来表示策略是为了方便读者理解,后续会考虑统一符号(加上对应注解);
关于体系的问题,其实是从不同的角度来讲解知识,后面会考虑统一风格
