题目:Selection of the number of change-points:Consistency and error rate control

报告人:邹长亮 教授 南开大学 统计与数据科学学院

主持人:刘玉坤教授

摘要:

In multiple change-point analysis, one of the main difficulties is to determine the number of change-points. In this talk, I will introduce a data-driven approach based on an order-preserved sample-splitting strategy. Under a unified framework, a cross-validation estimation scheme is developed to achieve consistent selection. Furthermore, we construct a simple yet effective selection procedure which is able to quantify “uncertainty”, say controlling the false discovery rate. The proposed methods are applicable to most kinds of popular change-point algorithms.
