WebIt's a clever way of semi-random sampling k objects that aren't too similar to be useful. If you only need a clever way of sampling, k-means may be very useful. This answer might be really meaningful if you show In high-dimensional data, distance doesn't work - elaborate it, in the specific context of clustering. WebTechniques for clustering high dimensional data have in-cluded both feature transformation and feature selection techniques. Feature transformation techniques attempt to summarize a dataset in fewer dimensions by creating com-binations of the original attributes. These techniques are very successful in uncovering latent structure in datasets.
