Definitions

Adaptive Windowing is a technique used for the online analysis of data streams to manage changes in the distribution of the data. It uses the standard idea of sliding window over the data, but, unlike other approaches, the size of the window is not fixed and set a priori but changed dynamically as a function of the data. The window is maintained at all times to the maximum length consistent with the assumption that there is no change in the data contained in it.

Context

Many modern sources of data are best viewed as data streams: a potentially infinite sequence of data items that arrive one at a time, usually at high and uncontrollable speed. One wants to perform various analysis tasks on the stream in an online, rather than batch, fashion. Among these tasks, many consist of building models such as creating a predictor, forming clusters, or discovering frequent patterns. The source of data may evolve over time, that is, its statistical properties...
