Get the best run from a stabilised NMF result

Extracts the run with the lowest reconstruction loss and returns it as a single-run NmfResult for downstream methods.

Usage

get_best_run(x)

# S3 method for class 'StabilisedNmfResult'
get_best_run(x)

Arguments

x

StabilisedNmfResult object.

Value

An NmfResult containing the W/H of the best run.

Examples

# the restart with the lowest reconstruction loss
sc <- demo_single_cells()
res <- stabilised_nmf_sc(sc, k = 5L, n_runs = 5L, .verbose = FALSE)
get_best_run(res)
