<p>Marvel几乎是所有Elasticsearch用户的标配。Marvel保留观测数据的代价是，<br>它默认每天会新建一个index，命名规律像是这样：.marvel-2017-12-10。<br>marvel自建的索引一天可以产生大概500M的数据，而且将会越来越多，占的容量也将越来越大。<br>有没有什么办法能让它自动过期？比如说只保留最近两天的观测数据，其他的都抛弃掉。</p>
<p>当然有办法,curator就可以帮你实现.<br>

<p>朴素贝叶斯就是利用先验知识来解决后验概率，因为训练集中我们已经知道了每个单词在类别0和1中的概率，即p(w|c),<br>我们就是要利用这个知识去解决在出现这些单词的组合情况下，类别更可能是0还是1,即p(c|w)。<br>如果说之前的训练样本少，那么这个p(w|c)就更可能不准确，所以样本越多我们会觉得这个p(w|c)越可信。<br>
