Method Detail

cluster

public DoubleDBSCANClusters cluster(double[][] data)

Description copied from interface: SpatialClusterer

Perform clustering on the given data.

Specified by:

cluster in interface DataClusterer<double[][],DoubleDBSCANClusters>

Specified by:

cluster in interface SpatialClusterer<DoubleDBSCANClusters,double[]>

Parameters:

data - the data.

Returns:

the generated clusters.

cluster

public DoubleDBSCANClusters cluster(DataSource<double[]> data)

Description copied from interface: SpatialClusterer

Perform clustering with data from a data source. The DataSource could potentially be backed by disk rather in memory.

Specified by:

cluster in interface SpatialClusterer<DoubleDBSCANClusters,double[]>

Parameters:

data - the data.

Returns:

the generated clusters.

performClustering

public int[][] performClustering(double[][] data)

Specified by:

performClustering in interface Clusterer<double[][]>

Returns:

Given data items, cluster them by index

getEps

public double getEps()

Returns:

the epse parameter

toString

public String toString()

Overrides:

toString in class Object
