Making a Cylinder-Bell-Funnel dataset

This example shows how to generate a Cylinder-Bell-Funnel dataset. This simulated dataset was introduced by N. Saito in his Ph.D. thesis entitled “Local feature extraction and its application”. It is one of the most well-known datasets in time series classification. It is implemented as pyts.datasets.make_cylinder_bell_funnel().
