Fix for from_data method with non-default indices.

Bugs:

  • BUG: cluster centers empty due to index mismatch (#19)

Version 0.5.0 (May 11, 2021)#

  • ENH: support hierarchical clustering using scipy (#11)

  • ENH: from_data and from_centers methods (#12)

Version 0.3.0 (January 31, 2021)#

API changes:

  • pca_weighted is now keyword of Clustergram.plot() not __init__.

Enhancements:

  • Support MiniBatchKMeans (scikit-learn)

  • Custom __repr__

  • Expose cluster labels obtained during the loop

  • Expose cluster centers

  • Silhouette score

  • Calinski and Harabasz score

  • Davies-Bouldin score

Version 0.2.0 (December 21, 2020)#

Version 0.2.0 brings support of Gaussian Mixture Models (using scikit-learn) and few minor changes.

Enhancements:
