Hierarchical Quickest Change Detection via Surrogates

31 Mar 2016Prithwish ChakrabortySathappan MuthiahRavi TandonNaren Ramakrishnan

Change detection (CD) in time series data is a critical problem as it reveal changes in the underlying generative processes driving the time series. Despite having received significant attention, one important unexplored aspect is how to efficiently utilize additional correlated information to improve the detection and the understanding of changepoints...
