Compare Baseline Performance With and Without Shuffled Labels

Source: R/plot_ml.R

Produces a bar plot comparing balanced accuracy for each antibiotic using true AMR labels vs. randomly shuffled labels.

plotBaselineComparison(non_shuffled_label_results, shuffled_label_results)

Arguments

non_shuffled_label_results

A performance tibble with antibiotic and bal_acc columns (one row per antibiotic), such as an aggregated performance_tibble from runMLPipeline(shuffle_labels = FALSE).

shuffled_label_results

The corresponding shuffled-label performance tibble, e.g. from runMLPipeline(shuffle_labels = TRUE).

Value

A barplot comparing balanced accuracy across antibiotics.

Examples

non_shuffled <- tibble::tibble(
  antibiotic = c("AMP", "CIP", "CRO"),
  bal_acc    = c(0.88, 0.81, 0.92)
)
shuffled <- tibble::tibble(
  antibiotic = c("AMP", "CIP", "CRO"),
  bal_acc    = c(0.52, 0.49, 0.55)
)
plotBaselineComparison(non_shuffled, shuffled)
