The weighted nearest neighbor rule for class dependent sample sizes (Corresp.)

The nearest neighbor rule is considered for data samples obtained by selecting independent samples with the conditional distribution corresponding to class . It is shown that a weighted distance rule can The nearest neighbor nde is considered for data samples obtained by selecting independent samples with the conditional distribution corresponding to class . It is shown that a weighted distance rule can improve the performance when the ratio of to the total sample size differs substantially from the probability of class .
