From our experiments we know that

  • The Laplacian Kernel works well on some scaled/normalized data.
  • The Exponential Kernel generally behaves the same of the Gaussian one, but in some situations makes the difference, as happened in the experiments with IRIS data (multivariate) or CLASSIC3 data (text documents in BOW model with TF-IDF encoding).

These results suggest to go deeper in the matter and explore other kernels that can be useful in clustering with SVC.

text documents that can be used for text mining applications. MC provides
an efficient multi-threaded implementation that can process very
large document collections. For example, MC took 1,189 seconds using
only 17.5 MBytes of main memory to process a sample collection of
about 114,000 documents (the experiment was run on a Sun Ultra10
workstation). More details on MC and its use in a fast clustering
algorithm are available in
this paper.
