摘要
针对大坝安全监测数据存在的多重共线性问题,利用岭回归方法建模,并采用遗传算法优化岭参数k。实例结果表明,基于遗传算法优化的岭回归较传统的最小二乘法更合理,结果更符合实际。
Aiming at the multi-collinearity problems of dam safety monitoring data,this paper applies the ridge estimate method to make regression analysis and the ridge parameter is optimized by using genetic algorithm.The instance results show that the ridge estimate based on genetic algorithm is more reasonable than the least squares method and the results are accord with the project examples.
