Application of Association Rules in Medical Data Analysis

Mainly introduces the way to discover asso ciation rules in medical data .In this paper, characteristics of medical data ar e analyzed. An example about a small medical data set of heart disease is given to explain how to map medical data to a transaction format containing items. Be cause of some problems existing in the application of association rules in medic al data analysis,an improved Apriori algorithm is introduced to solve them. Thr ough testing it is shown from results that the algorithm outperforms Apriori alg orithm. The results show that by using this algorithm some useful medical rules are validated.
