短通信：检测可能频繁的变化点：野生二进制分割2
Short Communication: Detecting Possibly Frequent Change-points: Wild Binary Segmentation 2
摘要：
这篇文章评论了wild binary segmentation 2的新版本。Wild Binary Segmentation 2和Steepest-drop模型选择在变点分析方面做出了改进，特别是在降低计算成本方面。然而，WBS 2倾向于高估WBS，并且阈值在没有变化点的短序列上不适当地工作。
英文摘要：
This article comments on the new version of wild binary segmentation 2. Wild Binary Segmentation 2 and Steepest-drop Model Selection has made improvements on changepoint analysis especially on reducing the computational cost. However, WBS2 tends to overestimate as WBS and the threshold does not work appropriately on short sequences without changepoints.
