R 中运行 h2o.deeplearning 算法出错

Question

我在运行 R 中的 H2O 深度学习中执行此命令时遇到错误：

model <- h2o.deeplearning(x = x, y = y, seed = 1234,
                          training_frame = as.h2o(trainDF),
                          nfolds = 3, 
                          stopping_rounds = 7, 
                          epochs = 400,
                          overwrite_with_best_model = TRUE,
                          activation = "Tanh",
                          input_dropout_ratio = .1,
                          hidden = c(10,10),
                          l1 = 6e-4,
                          loss = "automatic",
                          distribution = 'AUTO',
                          stopping_metric = "MSE")

错误如下：

Error in h2o.deeplearning(x = x, y = y, seed = 1234, training_frame = as.h2o(trainDF), : unused arguments (training_frame = as.h2o(trainDF), stopping_rounds = 7, overwrite_with_best_model = TRUE, distribution = "AUTO", stopping_metric = "MSE")

Answer 1

我无法重现您的特定错误，但我可以通过将 loss="automatic" 更新为 loss="Automatic" 来让代码在我这边工作（请注意 loss 它区分大小写）。
