摘要
以某城市需水量为研究对象,运用改进的支持向量基模型对该地区1991年到2001年的用水量进行模拟计算,并用该市2002年和2003年的用水量进行模型检验,与GM(1.1)模型所得的结果作比较,分析证明了改进的SVR模型方法能取得更好的结果。
City water used is selected as the study object. The Improvement Support vector machine method is applied to the simulation computation of the materials about water used from 1991 to 2001. The data series of 2002 -2003 are used to validate model. Compared with Gray model, the results of Improvement Support vector machine model show a better rational and available.
