This model has r nrow(param)
tuning parameters:
param$item
mtry
depends on the number of columns and the model mode. The default in [h2o::h2o.randomForest()] is floor(sqrt(ncol(x)))
for classification and floor(ncol(x)/3)
for regression.
[agua::h2o_train_rf()] is a wrapper around [h2o::h2o.randomForest()].
rand_forest( mtry = integer(1), trees = integer(1), min_n = integer(1) ) %>% set_engine("h2o") %>% set_mode("regression") %>% translate()
min_rows()
and min_cols()
will adjust the number of neighbors if the chosen value if it is not consistent with the actual data dimensions.
