| Description: | The data consist of "pseudo" time series obtained by converting two-dimensional shapes into one-dimensional time series (see [1], [2]). There are five classes corresponding to different shapes.
Class 1: Arrowhead
Class 2: Butterfly
Class 3: Fish
Class 4: Seashell
Class 5: Shield
We make two datasets out of these data. The two datasets share a same test set and only differ in the number of training instances. Original data created by Eamonn Keogh (see [1], [2]). Data edited by Hoang Anh Dau. Image from [1].
