| 摘 要： | 在研究和分析现有的Apriori算法后，提出一种新的改进算法。该算法在哈希表存放数据库的基础上，采用二进制的改进模型。在统计查找频繁项集的支持计数中，通过二进制位与运算代替链表间查找相同内容的节点运算。为提高内存分配和释放效率，文中采用内存池技术，有效地减少内存碎片和缺页中断，采用二进制的改进模型和内存池技术相结合，明显提高了客户满意度评测系统的效率。

| Abstract: | After analyzing and studying the previously existing Apriori algorithm,an improved algorithm is proposed.Based on the Hash table technique,the improved algorithm utilizes binary improved model.On the process of finding the frequent item sets,replace the node computation of finding the same context in the linked-tables by using binary and operator.For the sake of the efficience of memory allocate and memory release,memory pool technology employed in this paper.Memory pool can reduce the memory debris and mis... |
