| Abstract: | class cover catch digraphs based on proximity between training observations. Performance comparisons are presented on synthetic and real examples versus k-nearest neighbors, Fisher's linear discriminant and support vector machines. We demonstrate that the proposed semiparametric classifier has performance approaching that of the optimal parametric classifier in cases for which the optimal is available for comparison. |
