param: Get or set GP model parameters

Description

get_param returns the current hyperparameters of the GP model in a vector. set_param can be used to set the parameters. Note that these functions are intended mainly for internal usage, and there is typically no need to use these functions directly but instead create a new GP model using gp_init.

Usage

get_param(object, ...)
set_param(object, param, ...)

Value

get_param returns the current hyperparameters and set_param the GP model structure with the new parameter values.

Arguments

object

The model object.

...

Ignored currently.

param

The parameters to be set. Call first get_param to see the order in which the parameters should be given for a particular model. Notice that all positive parameters should be given in a log-scale.

Examples

# Set up some model
gp <- gp_init(cf = cf_sexp(), lik = lik_gaussian())

# print out to see the parameter ordering
param <- get_param(gp)
print(param)

# set some new values
param_new <- log(c(0.1, 0.8, 0.3))
names(param_new) <- names(param)
gp <- set_param(gp, param_new)

# check the result
print(get_param(gp))
