TimeSeriesKShapes

class TimeSeriesKShapes(n_clusters: int = 8, init_algorithm: str | ndarray = 'random', n_init: int = 10, max_iter: int = 300, tol: float = 0.0001, verbose: bool = False, random_state: int | RandomState = None)[source]

K-shape clustering for time series, from tslearn.

Direct interface to tslearn.clustering.KShape.

Parameters:

n_clusters: int, defaults = 8: The number of clusters to form as well as the number of centroids to generate.
init_algorithm: str or np.ndarray, defaults = ‘random’: Method for initializing cluster centers. Any of the following are valid: [‘random’]. Or a np.ndarray of shape (n_clusters, ts_size, d) and gives the initial centers.
n_init: int, defaults = 10: Number of times the k-means algorithm will be run with different centroid seeds. The final result will be the best output of n_init consecutive runs in terms of inertia.
max_iter: int, defaults = 30: Maximum number of iterations of the k-means algorithm for a single run.
tol: float, defaults = 1e-4: Relative tolerance with regards to Frobenius norm of the difference in the cluster centers of two consecutive iterations to declare convergence.
verbose: bool, defaults = False: Verbosity mode.
random_state: int or np.random.RandomState instance or None, defaults = None: Determines random number generation for centroid initialization.

Attributes:

labels_: np.ndarray (1d array of shape (n_instance,)): Labels that is the index each time series belongs to.
inertia_: float: Sum of squared distances of samples to their closest cluster center, weighted by the sample weights if provided.
n_iter_: int: Number of iterations run.
