WebSep 28, 2016 · SVMs achieve sparsity via the maximum margin (classification) or the epsilon-tube (regression) approach, which is geometrically intuitive. RVM, on the other hand, achieves sparsity via special priors and uses a nontrivial approximate optimization of partial posteriors, which is arguably more complex.
