normalized mean absolute error -回复 什么是标准平均绝对误差(NMSE)。 标准平均绝对误差(NMSE)是评估预测模型准确性的一种常用指标。它是一种衡量预测值与实际值之间误差的统计量,常用于评估回归模型的性能。在机器学习和统计分析中,预测模型的目标是生成最佳的预测结果,从而使得预测值与实际值之间的误差最小化。
A closed-form expression and an upper bound are obtained for the mean absolute error of the unbiased estimator of p. The results given permit the estimation of an arbitrary probability with a prescribed level of normalized mean absolute error....

Following convention, quantity terms were normalized using the data means to have mean values of one. Diamond found a negative relationship between aging and productivity and that the mean peak age for the citation stock for the six samples was 59 years of age. We then calculated the mean mult...
Normalized RMSE(Root Mean Square Error)是一种常用的模型评估指标,通常用于评估模型的预测精度。它是RMSE的标准化版本,可以将不同数据集的RMSE值进行比较。 Normalized RMSE的计算方法如下: NRMSE = \frac{RMSE}{y{\max} - y{\min}} 其中,RMSE是均方根误差,y{\max}和y{\min}分别是真实值的最大值和最...
