Abstract: Utilizing association rule discovery method to construct classification systems in data mining is known as associative classification.Existing AC techniques mine the training data set as whole in order to produce the outcome.An Incremental Upda-
ting algorithm applied to AC technique（IUAC）is introduced.The algorithm is based on the FP-growth to mine and update the association rules.And it applies a tree structure to store the association rules which are mined for classification.Moreover，in this paper，it adds more appropriate constraints in rule ranking procedure in order to control the number of class associative rules and improve the predictive accuracy.And finally，some analyses to the new algorithm are offered.
