Dqn forward

WebApr 19, 2024 · In a DQN, which uses off-policy learning, they represent a refined estimate for the expected future reward from taking an action a in state s, and from that point on following a target policy. The target policy in Q learning is based on always taking the maximising action in each state, according to current estimates of value.

Web为什么需要DQN我们知道，最原始的Q-learning算法在执行过程中始终需要一个Q表进行记录，当维数不高时Q表尚可满足需求，但当遇到指数级别的维数时，Q表的效率就显得十分有限。因此，我们考虑一种值函数近似的方法，实现每次只需事先知晓S或者A，就可以实时得到其对应的Q值。 phentermine regulations https://merklandhouse.com
