Unified Conversational Recommendation Policy Learning via Graph-based Reinforcement Learning

图的作用: 图结构捕捉不同类型节点(即用户、项目和属性)之间丰富的关联信息,使我们能够发现协作用户对属性和项目的偏好。因此,我们可以利用图结构将推荐和对话组件有机地整合在一起,其中对话会话可以被视为在图中维护的节点序列,以动态地利用对话历史来预测下一轮的行动。 由四个主要组件组成:基于图的 MDP ......

Luogu CF633B 【A Trivial Problem】题解

一段理解起来特别容易的代码 (目前来看是最短的) ## 思路 由于末尾0的个数就是阶乘中分解出10的个数,也就是分解出2的个数与5的个数中的最小值; 显然5的个数小于2的个数,即找出分解出的5的个数。 **比较容易推出:当 $n$ 为 $5^{k}$ 的倍数时,其阶乘分解出 $5$ 的个数即为 $n ......
