Description: The Code Project is an exciting site with impressive teaching and professional exchange capabilities. I have learned much from it and also decided to submit my contribution. Occasionally I was involved in a project to check experimental data for consistency. The data were collected in several binary files, which also contain \"holes\", i.e. missing data segments. The main idea to simplify the fast check report was to embed this report inside the progress control.-The Code Project is an exciting site with im pressive teaching and professional exchange c apabilities.

Description: 自适应GA SVM 参数选择算法研究Param eter selection algorithm for support vector machines based
on adaptive genetic algorithm
支持向量机是一种非常有前景的学习机器, 它的回归算法已经成功地用于解决非线性函数的逼近问题. 但
是, SVM 参数的选择大多数是凭经验选取, 这种方法依赖于使用者的水平, 这样不仅不能获得最佳的函数逼近效果,
而且采用人工的方法选择 SVM 参数比较浪费时间, 这在很大程度上限制了它的应用. 为了能够自动地获得最佳的
SVM 参数, 提出了基于自适应遗传算法的 SVM 参数选取方法. 该方法根据适应度值自动调整交叉概率和变异概率,
减少了遗传算法的收敛时间并且提高了遗传算法的精度, 从而确保了 SVM 参数选择的准确性. 将该方法应用于船用
锅炉汽包水位系统建模, 仿真结果表明由该方法所得的 SVM 具有较简单的结构和较好的泛化能力, 仿真精度高, 具
有一定的理论推广意义.- The support vector m achine ( SVM ) is a prom ising artificia l inte lligence technique, in w hich the regres
