A framework for data stream modeling and associated data mining tasks such as clustering and classification. The development of this package was supported in part by NSF IIS-0948893 and NIH R21HG005912.
Additional packages in the stream family are:
Stable CRAN version: install from within R with
Current development version: Download package from AppVeyor or install from GitHub (needs devtools).
Load the package and create micro-clusters via sampling.
library("stream") stream <- DSD_Gaussians(k=3, noise=0) sample <- DSC_Sample(k=20) update(sample, stream, 500) sample
Reservoir sampling Class: DSC_Sample, DSC_Micro, DSC_R, DSC Number of micro-clusters: 20
Recluster micro-clusters using k-means and plot results
kmeans <- DSC_Kmeans(k=3) recluster(kmeans, sample) plot(kmeans, stream, type="both")
