 sklearn.cluster.mean_shift   sklearn.cluster.mean_shift(X, *, bandwidth=None, seeds=None, bin_seeding=False, min_bin_freq=1, cluster_all=True, max_iter=300, n_jobs=None)[source]
 
Perform mean shift clustering of data using a flat kernel. Read more in the User Guide.  Parameters:
 
 
Xarray-like of shape (n_samples, n_features)


Input data.  
bandwidthfloat, default=None


Kernel bandwidth. If bandwidth is not given, it is determined using a heuristic based on the median of all pairwise distances. This will take quadratic time in the number of samples. The sklearn.cluster.estimate_bandwidth function can be used to do this more efficiently.  
seedsarray-like of shape (n_seeds, n_features) or None


Point used as initial kernel locations. If None and bin_seeding=False, each data point is used as a seed. If None and bin_seeding=True, see bin_seeding.  
bin_seedingbool, default=False


If true, initial kernel locations are not locations of all points, but rather the location of the discretized version of points, where points are binned onto a grid whose coarseness corresponds to the bandwidth. Setting this option to True will speed up the algorithm because fewer seeds will be initialized. Ignored if seeds argument is not None.  
min_bin_freqint, default=1


To speed up the algorithm, accept only those bins with at least min_bin_freq points as seeds.  
cluster_allbool, default=True


If true, then all points are clustered, even those orphans that are not within any kernel. Orphans are assigned to the nearest kernel. If false, then orphans are given cluster label -1.  
max_iterint, default=300


Maximum number of iterations, per seed point before the clustering operation terminates (for that seed point), if has not converged yet.  
n_jobsint, default=None


The number of jobs to use for the computation. This works by computing each of the n_init runs in parallel. None means 1 unless in a joblib.parallel_backend context. -1 means using all processors. See Glossary for more details.  New in version 0.17: Parallel Execution using n_jobs.     Returns:
 
 
cluster_centersndarray of shape (n_clusters, n_features)


Coordinates of cluster centers.  
labelsndarray of shape (n_samples,)


Cluster labels for each point.     Notes For an example, see examples/cluster/plot_mean_shift.py.
