<p>平衡业务策略与模型之间的关系。策略能力有限，模型也“没有银弹”。</p>
</blockquote><p>最近刚好在研究策略和多样性的关系，就帮DataFunTalk社区又整理了一篇稿子，策略本身很乏味，但是策略可以解决很多模型解决不了的问题。<br>为什么会这样呢？主要还是模型太笨了，由于模型不能完全动态的掌握用户的心理变化，兴趣变化，所以一般的推荐模型都是对于用户的基于历史的点击率CTR预估，可以简化为分类或者回归模型。可是实际上，远远没有这么简单。我觉得最接近”智能化的推荐“的算法就应该是强化学习，算法推出一个item就是一次尝试，用户的行为会及时让系统收到反馈，无论是”多样性“，”准确性“，”兴趣偏好“，”负反馈“，统统都会被融合到Agent的激励里。之后有空了希望进一步调研强化学习在推荐的瓶颈。<br>以下为分享内容。</p>
