Title: Graph-based Change-point Detection for Non-Euclidean and Multivariate Data


We present a new framework for the detection of change-points. The approach utilizes similarity information among observations and can be applied to sequences of multivariate or non-Euclidean data. Both offline and online detection will be discussed and analytical ways to determine the threshold of claiming a change are also provided, making the methods easy-off-the-shelf tools for real applications.
