查询词典 implement

The optimization methods of database SQL query were studied and some available query optimization Methods were given out as follows: The incompatible data type should avoid to be used; More redundancy search parameters should be given as join condition in join query; In some condition, the number of note hitted to target was estimated by optimizing implement using the average density; Some other maths operating symbol should avoid to be used as condition parameters in WHERE clause; Some operating symbol and its sentence should avoid to be used also; When the cluster function was used,the WHERE clause should be paied attention to more,and so on.

作者单位：（重庆工学院商贸信息学院，重庆 400050）摘要：数据库SQL查询语句的优化，须注意：避免使用不兼容数据类型；连接查询中应多给连接条件提供一些冗余的搜索参数；某种条件下优化器只能使用其平均密度以估计命中的记录数；避免对WHERE子句中条件参数使用其它数学操作符；避免使用某些操作符及相应语句；聚簇函数的使用应注意WHERE子句。

In this paper we propose an approach to augment the algorithm described before to improve their performance by defining the conditional probability distribution of different composition of continuous and discrete attributes, and implement these new modified algorithms in Weka. To reduce the storage complexity of the AODE algorithm, we used the selective ensemble method to modify it.

在本文中我们提出了通过有效地定义条件概率分布来改善基于朴素贝叶斯分类器的改进算法的性能的方法，并在Weka的框架下实现了我们提出的改进算法，同时考虑到AODE算法较高的空间复杂度，我们利用选择性集成的思想对AODE算法进行了改进，以降低其存储空间复杂度。
