Class represents clustering algorithm CURE with KD-tree optimization.
CCORE option can be used to use the pyclustering core - C/C++ shared library for processing that significantly increases performance.
Example:
def pyclustering.cluster.cure.cure.__init__ | ( | self, | |
data, | |||
number_cluster, | |||
number_represent_points = 5 , |
|||
compression = 0.5 , |
|||
ccore = True |
|||
) |
Constructor of clustering algorithm CURE.
[in] | data | (array_like): Input data that should be processed. |
[in] | number_cluster | (uint): Number of clusters that should be allocated. |
[in] | number_represent_points | (uint): Number of representative points for each cluster. |
[in] | compression | (double): Coefficient defines level of shrinking of representation points toward the mean of the new created cluster after merging on each step. Usually it destributed from 0 to 1. |
[in] | ccore | (bool): If True then CCORE (C++ solution) will be used for solving. |
def pyclustering.cluster.cure.cure.get_cluster_encoding | ( | self | ) |

def pyclustering.cluster.cure.cure.get_clusters | ( | self | ) |

def pyclustering.cluster.cure.cure.get_means | ( | self | ) |
Returns list of mean values of each cluster.
Cluster index should be used for navigation between mean values.
def pyclustering.cluster.cure.cure.get_representors | ( | self | ) |
Returns list of point-representors of each cluster.
Cluster index should be used for navigation between lists of point-representors.
def pyclustering.cluster.cure.cure.process | ( | self | ) |
Performs cluster analysis in line with rules of CURE algorithm.
