The doubly regularized support vector machine
WebIn this paper, we propose a doubly regularized support vector machine (DrSVM). The DrSVM uses the elastic-net penalty, a mixture of the L2-norm and the L1-norm penalties. By doing … Webrespectively, with the diagonal-form R e = D(b) = diag(b), in which the K × 1 vector b of the principal diagonal is composed of elements b k = 〈 e k e k * 〉 and the superscript + defines the Hermitian conjugate when stands with a matrix (or a vector). The vector b is referred to as a vector-form representation of the SSP, i.e., the SSP vector.

WebStandard SVMs do not provide such probabilities. One method to create probabilities is to directly train a kernel classifier with a logit link function and a regularized maximum likelihood score. However, training with a maximum likelihood score will produce non-sparse kernel machines.
