v0.3.0¶

June 2023

Following this release the deprecation policy remains suspended. Future releases may have breaking changes, so it may be wise to set an upper bound on the package version.

Highlights¶

An interface to the MrSQM algorithm has been added to the classification module.
k-NN estimators and the Elastic Ensemble classifier now support unequal length series.
The SAX transformation has been refactored to improve performance.
A new collection transformer base class has been added to the transformations module for more efficient transformation using collections of time series.
A rework of the benchmarking module has begun, starting with the introduction of functionality from kotsu
