Detailed Description

Provides service to change clustering result representation.

Example:

# load list of points for cluster analysis
sample = read_sample(path);

# create instance of K-Means algorithm
kmeans_instance = kmeans(sample, [ [0.0, 0.1], [2.5, 2.6] ]);

# run cluster analysis and obtain results
kmeans_instance.process();
clusters = kmeans_instance.get_clusters();

# by default k-means returns representation CLUSTER_INDEX_LIST_SEPARATION
type_repr = kmeans_instance.get_cluster_encoding();
encoder = cluster_encoder(type_repr, clusters, sample);

# change representation from index list to label list
representor.set_encoding(type_encoding.CLUSTER_INDEX_LABELING);

# change representation from label to object list
representor.set_encoding(type_encoding.CLUSTER_OBJECT_LIST_SEPARATION);
