Create a Value Sampler for Random Parameters

This function returns a 0 argument function that can be used as a generator function in the random.params argument of the param.net function.

Usage

param_random(values, prob = NULL)

Arguments

values

A vector of values to sample from.

prob

A vector of weights to use during sampling. If NULL, all values have the same probability of being picked (default = NULL).

Value

A 0 argument generator function to sample one of the values from the values vector.

Examples

# Define function with equal sampling probability
a <- param_random(1:5)
a()
#> [1] 4

# Define function with unequal sampling probability
b <- param_random(1:5, prob = c(0.1, 0.1, 0.1, 0.1, 0.6))
b()
#> [1] 2
