改进的GMDH方法--原始变量保存算法
An Improved GMDH Algorithm--The Initial Variable-Keeping Algorithm
-
摘要: 本文在GMDH算法的基础上,研究了中间变量数目的合适取值问题;提出了原始变量保 存的GMDH算法;分析了改进算法的特点.计算机仿真表明,改进的GMDH算法较原算法有 更高的可靠性和灵活性,并可减少计算量和计算机内存容量.Abstract: Based on the self-organizing GMDH algorithm, the paper studies the proper range of the number of intermediate variables selected. An improved GMDH algorithm which keeps the initial variables is given. Features of this algorithm are analysed. Computer simulation shows that the improved GMDH algorithm is more reliable and flexible than the original algorithm, and demands much less calculation and computer memory.
