Mike Schultz and I did some experiments with SVMs for TDT tracking.
The results were significantly inferior to a TF/IDF baseline.
I believe that we reported on this at one of the TDT meetings several years
ago.
Of course there are many details that could have been done differently,
and so perhaps a different version of SVMs would have done better, but
our evaluation was that the technique itself is not particularly
promising for this application.
