PEREZ HERNANDEZ, Lucas; MORA FLOREZ, Juan  y  BEDOYA CEBAYOS, Juan. A linear approach to determining an SVM-based fault locator’s optimal parameters. Ing. Investig. [online]. 2009, vol.29, n.1, pp.76-81. ISSN 0120-5609.

The setting up process for support vector machines (SVM) is discussed in this paper. Such settings are normally obtained from exhaustive testing of SVM, settled on by using several configuration parameter values and evaluating performance by using techniques such as cross validation. The linear approach presented in this paper is based on redefining the classical SVM second-order objective function. Better setting parameters were obtained by using low computational cost methodology for resolving new linear optimisation. The proposed approach was applied to a typical classification problem regarding fault location in power distribution systems; the results so obtained were compared to those obtained using classical methodology. An 80% improvement was achieved in mean error when estimating fault location and 56% reduction in the computing time needed for ob-taining the best results when using classical approaches.

Palabras clave : euclidean distance norm; linear programming; fault location; support vector machine.
