The Bayesian classification approach assume that its attribute is independent

so the feature reduction of condition attribute set must be handled in data preprocess.In this process

data classification will not be accurate ifit can not be handled properly.In this paper

random selected attributes of the training sets are used to form particles and a fitness function is set up at the same time

and therefore the naive Bayesian classifiers is constructed.At the same time

QPSO algorithm is used to optimize the ef...
