为解决此问题,考虑使用对数RMSE(logarithmic RMSE)。先取对数操作,可以稍微缓解大值误差对整体评估的影响。RMSE在预测值分布固定时,评估结果较为合理。然而,对数转换后的RMSE同样存在适用范围限制,其效果依赖于数据特性。
假如真实值为1000,若果预测值是600,那么RMSE=400, RMSLE=0.510 假如真实值为1000,若预测结果为1400...
RMSE就会很大。 相应的,如果另外一个比较差的算法对这一个大的值准确一些,但是很多小的值都有偏差,...

求助:用xgboost的eval_metric只有rmse,没有rmsle。怎么自定义?
[3] developed a health diagnostic and monitoring strategy for the planetary gear mechanism for single tooth cracks. The root mean square (RMS) values of the vibration data obtained from the planetary gear mechanism was collected and used as a fault indicator. Their study showed that the RMS ...
