摘要:
为了提高对医院监护中心历史数据的管理水平,为监护人员提供有力的决策支持,提出了一种针对该系统的改进Apriori算法。该算法引入了属性值度的概念,减少了找出频繁项集所需要的时间,也减少了扫描数据库的次数。为了验证改进Apriori算法的正确性、有效性和快速性,文中将改进的Apriori算法与传统的Apriori算法分别应用到医院监护中心系统中去,并对两种算法的效率进行了比较。结果表明,改进Apriori算法能够得到所需要的强关联规则,并在效率上有显著的提高,为监护人员更好控制患者的病情提供了很好的决策支持
Abstract:
To increase the level of hospital historical data management and provide a strong support for supervisors,an improved Apriori algorithm is proposed specific to this system. The improved algorithm brings in a concept of the attribute-value-degree,reduce the need time to find frequent itemsets,and also reduce the times of scanning database. In order to validate the correctness,effectiveness and speedi-ness of the new algorithm,both the new Apriori algorithm and the traditional Apriori algorithm are applied to this system,and the two al-gorithms are compared. The result shows that the new algorithm is able to dig useful and reasonable rules,has better performance in effi-ciency,and provides decision support of better control diseases to patients for supervisors
