Grid search with range of hyperparameters
In chapter 1, you learned how to use the expand.grid()
function to manually define a set of hyperparameters. The same function can also be used to define a grid with ranges of hyperparameters.
The voters_train_data
dataset has been loaded for you, as have the caret
and tictoc
packages.

Hyperparameter Tuning in R
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Define the grid with hyperparameter ranges
big_grid <- expand.grid(___ = ___(___ = 1, ___ = 5, by = ___),
decay = c(0, 1))
