h2o.glm lambda搜索未遍历所有lambda [英] h2o.glm lambda search not appearing to iterate over all lambdas
本文介绍了h2o.glm lambda搜索未遍历所有lambda的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
请考虑以下基本可复制示例:
Please consider the following basic reproducible example:
library(h2o)
h2o.init()
data("iris")
iris.hex = as.h2o(iris, "iris.hex")
mod = h2o.glm(y = "Sepal.Length", x = setdiff(colnames(iris), "Sepal.Length"),
training_frame = iris.hex, nfolds = 2, seed = 100,
lambda_search = T, early_stopping = F,
family = "gamma", nlambdas = 100)
运行上述命令时，我希望h2o会迭代100多个不同的lambda值.但是，运行length(mod@allparameters$lambda)将显示实际上仅测试了79个lambda值.这79个值是序列中的前79个值:
When I run the above, I expect that h2o will iterate over 100 different values of lambda. However, running length(mod@allparameters$lambda) will show that only 79 values of lambda were actually tested. These 79 values are the first 79 values in the sequence:
maxLambda = max(mod@allparameters$lambda)
lambdaMinRatio = mod@allparameters$lambda_min_ratio
exp(seq(log(maxLambda), log(maxLambda*lambdaMinRatio), length.out = 100))
您能否让我知道如何使该函数遍历所有100个lambda值? (我尝试设置early_stopping = F来查看是否可以解决问题，但不能解决问题.)
Could you please let me know how I can get the function to iterate over all 100 values of lambda? (I tried setting early_stopping = F to see if that would fix the issue but it does not.)
这是我的群集信息(如果有帮助的话):
Here is my cluster info if it helps:
R is connected to the H2O cluster:
H2O cluster uptime: 11 hours 21 minutes

谢谢！
根据要求，这是h2o.getGLMFullRegularizationPath(mod)的输出:

编辑#2:回应@Darren的回答.我现在在我的实际(机密)数据集上看到以下内容.交叉验证的模型选择了较小的lambda，但主要模型停在了很大的lambda.
EDIT #2: In response to @Darren's answer. I am now seeing the following on my actual (confidential) dataset. The cross-validated models have selected smaller lambda's, yet the main model stops at a very large lambda.

推荐答案
Short answer: you've found a bug and we've opened a ticket here. The early stopping flag is not being honored when nfolds > 0. In the meantime, if you don't set nfolds, you should get 100 lambdas.
这篇关于h2o.glm lambda搜索未遍历所有lambda的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
