| 摘 要： | 投影寻踪算法是水质评价中常用的模型,针对投影寻踪模型中存在的投影方向优化问题,提出了运用模糊自适应模拟退火遗传算法（FASAGA）来寻找最佳投影方向的方法。改进了现有的投影寻踪水质评价模型,分析了新模型的性能和特点,并应用该模型评价了惠州市的西湖水质。实验证明,该模型能有效地提高水质评价的速度和准确度。 |

| Abstract: | Projection pursuit algorithm is applied to water quality assessment.Due to the problem of projection direction optimization in the projection pursuit model,a fuzzy adaptive simulated annealing genetic algorithm(FASAGA) is presented to find the best projection direction.The existing water quality assessment model is improved,the performance and characteristics of the new model are analyzed,and the new model is used to evaluate the water quality of the West Lake in Huizhou City.Experiment results show that th... |
