The UnsupervisedShapelet function takes a set of time series and assigns them to clusters, based on the u_shapelets that it finds. The function uses these steps:

  1. Saxify the input data (as described in SAX2).
  2. Apply random masking to the input data.
  3. Use statistics to find u_shapelets.
  4. Use scores to find u_shapelets.
  5. Use the u_shapelets to cluster the times series.
