Tuning Parameters

#| label: h2o-param-info
#| echo: false
defaults <- 
  tibble::tibble(parsnip = c("penalty", "mixture"),
                 default = c("see below", "see below"))

param <-
poisson_reg() |> 
  set_engine("h2o") |> 
  make_parameter_list(defaults)

This model has r nrow(param) tuning parameters:

#| label: h2o-param-list
#| echo: false
#| results: asis
param$item

#| child: template-h2o-glm-penalty.Rmd
#| include: false

Translation from parsnip to the original package

[agua::h2o_train_glm()] for poisson_reg() is a wrapper around [h2o::h2o.glm()] with family = 'poisson'.

r uses_extension("poisson_reg", "h2o", "regression")

#| label: h2o-csl
library(poissonreg)

poisson_reg(penalty = double(1), mixture = double(1)) |> 
  set_engine("h2o") |> 
  translate()

Preprocessing requirements

#| child: template-makes-dummies.Rmd

#| child: template-same-scale.Rmd

By default, h2o::h2o.glm() uses the argument standardize = TRUE to center and scale all numerical columns.

Initializing h2o

#| child: template-h2o-init.Rmd

Saving fitted model objects

#| child: template-bundle.Rmd
