在h2o（随机森林）中合奏-多项式分布

Question

I have a problem with building an ensemble using h2o and Random Forest as one of the components. I estimate the models as in h2o 's documentation with the only difference being the dependent variable being a multiclass variable. When I try to build an ensemble I get the following error:

Error: water.exceptions.H2OIllegalArgumentException: Don't know how to set the distribution for a multinomial Random Forest classifier.

I tried googling it but with no success. Anyone knows what to do in such a case?

Answer 1

Multiclass support for Stacked Ensemble was only released very recently (in H2O 3.16.0.1), so you'll need to upgrade your H2O package for this to work.

You can use update.packages("h2o") to upgrade to the latest CRAN version.
