H2o模型性能指标并获得图表定制 [英] H2o model performance metric and gains chart customization

问题描述

我看到h2o模型性能度量包含AUC，对数损失等.有一个模型性能度量称为lift_top_group，它在十等分上升高吗?

I see h2o model performance metric contains AUC, logloss etc. There is one model performance metric called lift_top_group, is it lift on top decile?

用户还可以指定h2o的频带以输出增益图表，例如前5％，5％-10％，10％-15％.......我可以找到的功能是h2o.gainsLift

Also can user specify the band for h2o to output gains chart such as top 5%, 5%-10%, 10%-15% ....... The function I can find is h2o.gainsLift

推荐答案

您可以在输出中看到所有分位数组(Flow的显示效果很好).最高的组是最高的1％，lift_top_group是指该组.可用于提前停止.增益/提升图表中的所有其他信息可在所有二项式模型指标中使用，以进行检查.此处的更多信息: https: //github.com/h2oai/h2o-3/blob/master/h2o-docs/src/product/tutorials/GainsLift.md (请注意，图片已过时，它统一使用5％的间隔-现在顶部有更多的细粮组.

You can see all quantile groups in the output (Flow has a nice display). The top group is the top 1%, and lift_top_group refers to that. It can be used for early stopping. All other information from the gains/lift chart is available in all binomial model metrics for inspection. More info here: https://github.com/h2oai/h2o-3/blob/master/h2o-docs/src/product/tutorials/GainsLift.md (note that the picture is outdated, it uses 5% intervals uniformly - now there are more fine grain groups at the top).
