recluster: Re-clustering micro-clusters

Description

Use a macro clustering algorithm to recluster micro-clusters into a final clustering.

Usage

recluster(macro, dsc, type="auto", ...)

Arguments

macro

a macro clustering algorithm (class "DSC_Macro")

dsc

a DSC object containing micro-clusters.

type

controls which clustering is used from dsc (typically micro-clusters).

...

additional arguments passed on.

Value

• The object macro is altered and contains the clustering.

Details

Takes centers and weights of the micro-clusters and applies the macro clustering algorithm.

Examples

set.seed(0)
### create a data stream and a micro-clustering
dsd <- DSD_Gaussians(k=3, d=3)

micro <- DSC_Sample(k=50)
cluster(micro, dsd, 500)
micro
  
### recluster using k-means
kmeans <- DSC_Kmeans(k=3)
recluster(kmeans, micro)

### plot clustering
plot(kmeans, dsd, main="Macro-clusters (Sampling + k-means)")
