ArrowHead

ArrowHead

class ArrowHead(return_mtype='pd-multiindex')[source]

ArrowHead time series classification problem.

Example of a univariate problem with equal length series.

Notes

Dimensionality: univariate Series length: 251 Train cases: 36 Test cases: 175 Number of classes: 3

The ArrowHead dataset consists of outlines of images of arrowheads. The shapes of the projectile points are converted into a time series using the angle-based method. 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-normalized version of that used in Ye09shapelets. The three classes are called “Avonlea”, “Clovis”, and “Mix”.
