Our code is embedded within the Weka framework and the zip file contains all the necessary source code. It is also included in a Netbeans project, so you should be able to load this in directly. There is a helper class called ShapeletExamples (in the package examples) to illustrate the usage. The code includes classes for:

  • A shapelet tree algorithm based on that proposed in [1].
  • A shapelet transform algorithm as described in [4] that can use any one of four shapelet similarity measures.
  • A class to reproduce all the experiments described in [4]
  • Extended shapelet transforms that take advantage of the distance speed ups proposed in [1,2]

The latest version of the shapelet transform is available in Java from here:

And in python, you can find shapelets here:
