【唐】 牛峤

鵁鶄飞起郡城东。碧江空，半滩风。越王宫殿，蘋叶藕花中。帘卷水楼鱼浪起，千片雪，雨蒙蒙。

【五代】 徐昌图

饮散离亭西去，浮生常恨飘蓬。回头烟柳渐重重。淡云孤雁远，寒日暮天红。 今夜画船何处？潮平淮月朦胧。酒醒人静奈愁浓。残灯孤枕梦，轻浪五更风。

【宋】 王沂孙

渐新痕悬柳，淡彩穿花，依约破初暝。便有团圆意，深深拜，相逢谁在香径。画眉未稳。料素娥、犹带离恨。最堪爱、一曲银钩小，宝帘挂秋冷。 千古盈亏休问。叹慢磨玉斧，难补金镜。太液池犹在，凄凉处、何人重赋清景。故山夜永。试待他、窥户端正。看云外山河，还老尽、桂花影。

【宋】 金德淑

春睡起，积雪满燕山。万里长城横缟带，六街灯火已阑珊，人立玉楼间。

Actor-critic methods are still policy gradient methods. Compared to REINFORCE, actor-critic methods use TD learning to approximate the action value \(q_\pi\left(s_t, a_t\right)\).

What are "actor" and "critic"?

• Here, "actor" refers to policy update. It is called actor is because the policies will be applied to take actions.
• Here, "critic" refers to policy evaluation or value estimation. It is called critic because it criticizes the policy by evaluating it.
