I want to cluster them using Birch clustering algorithm. Does this method have 'precomputed' option.
No it doesn't, see http://scikit-learn.org/stable/modules/generated/sklearn.cluster.Birch.html so you would need to provide it with the original features matrix (not the precomputed distance matrix). Since your dataset is fairly small, there is no reason in precomputing it anyway.
I needed train an SVM on the centroids of the microclusters so *How can i get the centroids of the microclusters?*
By "microclusters" do you mean sub-clusters? If you are interested in the leaves subclusters see the Birch.subcluster_centers_ parameter.
Otherwise if you want all the centroids in the hierarchy of subclusters, you can browse the hierarchical tree via the Birch.root_ attribute then look at _CFSubcluster.centroid_ for each subcluster.
Hope this helps, -- Roman _______________________________________________ scikit-learn mailing list scikit-learn@python.org https://mail.python.org/mailman/listinfo/scikit-learn
