Create a Tuning Grid of Survival Learners

Dynamically generates custom wrapper functions for a specified base learner across a grid of hyperparameters.

Usage

create_grid(base_learner, grid_params)

Arguments

base_learner

Character string of the base learner function name (e.g., "surv.gbm").

grid_params

List of numeric/character vectors containing hyperparameter values.

Value

A character vector of class "SuperSurv_grid" containing the newly generated function names.

Details

Generated functions are assigned to the calling environment. The base learner is resolved there (with package functions as a fallback) when the grid is created and retained by each generated function. Local base learners and grids can therefore be used inside a function that calls SuperSurv(), without modifying the global environment.
