摘要翻译：
小概率事件检测是大数据中的一个关键问题。这类事件往往包括很少发生的现象，应该仔细检测和监测。在给定独立事件的先验概率和事件上观测数据的条件分布的情况下，贝叶斯检测可以用于估计观测数据背后的事件。已经证明，在平均意义上，贝叶斯检测具有最小的总体测试误差。然而，当检测到先验概率很小的事件时，条件贝叶斯检测会导致较高的漏检率。针对这一问题，提出了一种改进的基于贝叶斯检测和消息重要性度量的检测方法，在检测概率较小的情况下，可以降低漏检率。结果可以帮助挖掘大数据中的小概率事件。

英文摘要：
  The minor probability events detection is a crucial problem in Big data. Such events tend to include rarely occurring phenomenons which should be detected and monitored carefully. Given the prior probabilities of separate events and the conditional distributions of observations on the events, the Bayesian detection can be applied to estimate events behind the observations. It has been proved that Bayesian detection has the smallest overall testing error in average sense. However, when detecting an event with very small prior probability, the conditional Bayesian detection would result in high miss testing rate. To overcome such a problem, a modified detection approach is proposed based on Bayesian detection and message importance measure, which can reduce miss testing rate in conditions of detecting events with minor probability. The result can help to dig minor probability events in big data.
