ArrowHead

This dataset is part of the UCR Archive maintained by University of Southampton researchers. Please cite a relevant or the latest full archive release if you use the datasets. See http://www.timeseriesclassification.com/. The arrowhead data consists of outlines of the images of arrowheads. The shapes of the projectile points are converted into a time series using the angle-based method. The classification of projectile points is an important topic in anthropology. The classes are based on shape distinctions such as the presence and location of a notch in the arrow. The problem in the repository is a length normalised version of that used in Ye09shapelets. The three classes are called "Avonlea", "Clovis" and "Mix". http://alumni.cs.ucr.edu/~lexiangy/shapelet.html http://alumni.cs.ucr.edu/~lexiangy/Shapelet/Proj_Point_Review.pdf Donator: L. Ye, E. Keogh
