Combining absolute error function with relative error function , and setting it as the objective function of bp networks application to the flood forecast 综合绝对误差函数和相对误差函数于一体,提出一种适合于水文研究的bp神经网络综合目标函数。
The most important criteria that used to check the calibrated model are root mean square error ( rms ) , the mean absolute error normalized rms error , and mass balance 模型参数使用试错法识别,识别过程中最重要的指标是均方差、平均绝对误差、标准均方差和水均衡。
In order to minimize the value of the improved integral time multiplied absolute error ( itae ) performance index , the simplex method was used to optimize the fuzzy controller with 4 modifying factors 采用单纯形法对4修正因子模糊控制器的4个修正因子进行优化,以使改进的itae性能指标最小。
Results show that the rbfnn is obviously superior to the traditional linear model , and its mae ( mean absolute error ) and rmse ( root mean square error ) are 41 . 8 and 55 . 7 , respectively 结果显示,该模型预测效果明显优于传统的线性自回归预测模型,各月平均的平均绝对误差( mae )和均方误差( rmse )达到41 . 8和55 . 7 。
Its maximum absolute error is about ? 3g and maximum relative error is only about 0 . 4 % . evapotranspiration of tomato measured by our apparatus in laboratory during a consecutive period presents very well its change in reality 其测定值能较好地反映植物在短?段内的蒸散变化情况,是一种比较方便实用的测定盆栽植物蒸散的仪器。
