| 摘 要： | 为了对经济效益做出客观准确的评价,提出基于差分进化算法的支持向量回归机评价模型。以误差平方和最小为准则,用差分进化算法对支持向量回归机参数进行优化选择,然后利用改进的支持向量机对经济效益进行综合评价。试验结果表明,该模型能从整体上准确、客观地反映经济效益情况,评价结果更符合实际,更加科学合理。

| Abstract: | Evaluation model of economic efficiency is presented to improve the accuracy of evaluation based on DE-SVR.where optimal rule is the least sum of square error,the parameters of SVR are optimized by using differential evolution algorithm,Economic efficiency is evaluated based on SVR.The simulation result shows that the result of DE-SVR is actual,scientific and reasonable. |
