%description
Time series clustering along with optimized techniques related to the
Dynamic Time Warping distance and its corresponding lower bounds.
Implementations of partitional, hierarchical, fuzzy, k-Shape and TADPole
clustering are available. Functionality can be easily extended with custom
distance measures and centroid definitions. Implementations of DTW
barycenter averaging, a distance based on global alignment kernels, and
the soft-DTW distance and centroid routines are also provided. All
included distance functions have custom loops optimized for the
calculation of cross-distance matrices, including parallelization support.
Several cluster validity indices are included.
