在前两篇文章强化学习基础:基本概念和动态规划和强化学习基础:蒙特卡罗和时序差分中介绍的强化学习的三种经典方法(动态规划.蒙特卡罗以及时序差分)适用于有限的状态集合$\mathcal{S}$,以时序差分中的Q-Learning算法为例,一般来说使用n行(n = number of states)和m列(m= number of actions)的矩阵(Q table)来储存action-value function的值,如下图所示: 对于连续的状态集合$\mathcal{S}$,上述方法就不能适用
1. 前言 在前面的章节中我们介绍了时序差分算法(TD)和Q-Learning,当状态和动作空间是离散且维数不高时可使用Q-Table储存每个状态动作对的Q值,而当状态和动作空间是高维连续时,使用Q-Table不动作空间和状态太大十分困难.所以论文Human-level control through deep reinforcement learning提出了用Deep Q Network(DQN)来拟合Q-Table,使得Q-Table的更新操作包在一个黑盒里面,使强化学习的过程更加的通用化

摘要 新闻推荐系统中,新闻具有很强的动态特征(dynamic nature of news features),目前一些模型已经考虑到了动态特征. 一:他们只处理了当前的奖励(ctr);. 二:有一些模型利用了用户的反馈,如用户返回的频率.(user feedback other than click / no click labels (e.g., how frequentuser returns) ); 三:会给用户推送一些内容类似的新闻,用户看多了会无聊. 为了解决上述问题,我们提出了DQ
