Guyon et al. [ 1] proposed one of the most popular wrapper approaches for variable selection in SVM. The method is known as SVM-Recursive Feature Elimination (SVM-RFE) and, when applied to a linear kernel, the algorithm is based on the steps shown in Fig. 1. Prikaži več One of our proposed methods follows and extends the idea proposed in Krooshof et al. [12] and Postma et al. [13] to visualize the importance of … Prikaži več The RFE-pseudo-samples algorithm allows us to plot the decision values and the range of all variables, in this way we account for: 1. Strenght and direction of the association … Prikaži več We approach the problem of the interpretability of kernel methods by mapping simultaneously data points and relevant variables in … Prikaži več Reverter et al.

Feature selection is an important combinatorial optimisation problem in the context of supervised pattern classification. This paper presents four novel continuous feature selection approaches directly minimising the classifier performance. In particular, we include linear and nonlinear Support Vector …
