EuclideanClustering

class EuclideanClustering

Bases: etna.clustering.hierarchical.base.HierarchicalClustering

Hierarchical clustering with euclidean distance.

Examples

>>> from etna.clustering import EuclideanClustering
>>> from etna.datasets import TSDataset
>>> from etna.datasets import generate_ar_df
>>> ts = generate_ar_df(periods = 40, start_time = "2000-01-01", n_segments = 10)
>>> ts = TSDataset(TSDataset.to_dataset(ts), freq="D")
>>> model = EuclideanClustering()
>>> model.build_distance_matrix(ts)
>>> model.build_clustering_algo(n_clusters=3, linkage="average")
>>> segment2cluster = model.fit_predict()
>>> segment2cluster
{'segment_0': 2,
