Coding of non-stationary sources as a foundation for detecting change points and outliers in binary time-series

Sunehag, Peter; Shao, Wen; Hutter, Marcus


An interesting scheme for estimating and adapting distributions in real-time for non-stationary data has recently been the focus of study for several different tasks relating to time series and data mining, namely change point detection, outlier detection and online compression/sequence prediction. An appealing feature is that unlike more sophisticated procedures, it is as fast as the related stationary procedures which are simply modified through discounting or windowing. The discount scheme...[Show more]
