Forget the permutations for gips object optimized with save_all_perms = TRUE

Slim the gips object by forgetting the visited permutations from find_MAP(save_all_perms = TRUE).

Usage

forget_perms(g)

Arguments

g

An object of class gips. A result of a find_MAP(save_all_perms = TRUE).

Value

Returns the same object g as given, but without the visited permutation list.

Details

For example, perm_size = 150 and max_iter = 150000 we checked forget_perms() saves ~350 MB of RAM.

Examples

A <- matrix(rnorm(10 * 10), nrow = 10)
S <- t(A) %*% A
g <- gips(S, 13, was_mean_estimated = FALSE)
g_map <- find_MAP(g,
  max_iter = 10, optimizer = "Metropolis_Hastings",
  show_progress_bar = FALSE, save_all_perms = TRUE
)
