Abridged Symbolic Representation of Time Series for Clustering

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2019
In recent years a couple of methods aimed at time series symbolic representation have been introduced or developed. This activity is mainly justified by practical considerations such memory savings or fast data base searching.

An Optimal Linear Time Algorithm for Quasi-Monotonic Segmentation [PDF]

open access: yes, 2007
Monotonicity is a simple yet significant qualitative characteristic. We consider the problem of segmenting a sequence in up to K segments. We want segments to be as monotonic as possible and to alternate signs.
