Grid(size = 3, random = FALSE)

Arguments

size

single integer or vector of integers whose positions or names match the parameters in a model's tuning grid and which specify the number of values used to construct the grid.

random

number of unique points to sample at random from the grid defined by size. If size is a single unnamed integer, then random = Inf will include all values of all grid parameters in the constructed grid, whereas random = FALSE will include all values of default grid parameters.

Details

Returned Grid objects may be supplied to TunedModel for automated construction of model tuning grids. These grids can be extracted manually and viewed with the expand_modelgrid function.

Value

Grid class object.
