Moving archetypes

Research output: Contribution to journalArticlepeer-review

Abstract

We introduce a variation of the statistical method archetypal analysis (Cutler and Breiman, 1994) that tracks moving structures, such as traveling waves or solitons, in a data set. By using this method the traveling part of the motion is separated from the stationary (or semi-stationary) pattern.
