Checks if grid search needs to be performed. All tunable parameters should be passed to this function, individually or as a list. If any argument has more than one assigned values, the function returns TRUE, otherwise FALSE. This can be used to check whether gridSearchLearn must be run.
gridCheck(...)
Parameters; will be converted to a list
The idea is that if you know which parameter values you want to use, you define them
e.g. alpha = 0, lambda = .2
. If you don't know, you enter the set of values to be tested,
e.g. alpha = c(0, .5, 1), lambda = seq(.1, 1, .1)
.
