摘要
在继承原有算法思路的基础上,对ID3算法的核心部分进行改进,通过使用嵌入式SQL,直接对目标数据库进行查询操作并处理,最终得到分类决策表并保存于数据库。试验证明,改进的ID3算法结合SQL的高效性和C语言的灵活性,能高效无缝地实现大量数据的分类且大大提高算法的执行效率。摘要:
Proposes an improvement to the core section of ID3 based on the inherent ID3 algorithm.Using the embedded SQL,it directly queries the database and then processes received data,then finally acquires a decision table of classification.It is proved that with the improved ID3 combining the high efficiency of SQL and the flexibility of C language,can achieve the highly efficient and seamless classification of large data,and also greatly improve the processing efficiency.
