摘要
In this paper two Mahalanobis distance-based criteria are proposed for feature evaluation. Because of certain theoretical properties of these two criteria which are discussed in the paper, they are expected to perform better than the direct use of the Mahalanobis distance in a multiclass pattern recognition problem. Experimental results also suggest their superiority.
