摘要: In this paper, we propose an algorithm for learning a general class of similarity measures kNN classification. This encompasses, among others, the standard cosine measure, as well Dice and Jaccard coefficients. The is extension voted perceptron allows one to learn different types functions (either based on diagonal, symmetric or asymmetric matrices). results obtained show that yields significant improvements several collections, two prediction rules: rule, which was our primary goal, version it.
