前文已经涉及过Bayes估计的内容,此处再稍作回顾。 我们知道,对于一个估计问题,一致最优的估计是不存在的,所以为了能够得到一个合理的估计,需要限制估计类的范围,或者降低最优性的要求。前一种思路导出了常见…
就是经验贝叶斯（Empirical Bayes）的方法，从大量任务中学习任务的先验，期待这样的先验能够使我们的预测...
We generalize the approach of Liu and Lawrence (1999) for multiple changepoint problems where the number of changepoints is unknown. The approach is based on dynamic programming recursion for efficient calculation of the marginal probability of the data with the hidden parameters integrated out. For...

Bayesian inference is attractive for its coherence and good frequentist properties. However, it is a common experience that eliciting a honest prior may be difficult and, in practice, people often take an {\em empirical Bayes} approach, plugging empirica
漫谈统计学习之经验贝叶斯(Empirical Bayes) ©作者 |黄春喜 学校|香港科技大学 研究方向 |智能交通 1.1 前言 在传统的贝叶斯方法中,我们在获取到任何观测数据之前就已经有了确定的先验分布,然后利用观测数据对先验分布进行修正得到后验概率。举个很简单的例子:我在乘坐飞机之前就知道飞机失事的概率非常小,这个概率在...
