It has been verified in practical experiments that the classification performance can be improved by increasing the weights of misclassified training samples. We prove that in case of maximum-likelihood estimation the weighting of discrete data vectors is asymptotically equivalent to multiplication of the estimated distributions by a positive function. Consequently, the Bayesian decision-making can be made asymptotically invariant with respect to arbitrary weighting of data under certain conditions.
