Denoeux's evidence theoretic classifier needs to generate multiple mass functions, which are then combined and used for classification. The combination operation is known to be computationally expensive. A novel evidence theoretic classifier is proposed in this paper where only one mass function is needed to compute the class conditional probability for classification. Such a classifier extends the standard majority voting k-nearest neighbour classifier, and is an approximation of the Bayes classifier. This classifier is shown to perform better than the voting and distance weighted k-nearest neighbour classifiers. This work has led to a series of papers on neighbourhood counting methodology.
