plot_hp_performance: Plot hyperparameter performance metrics

Description

Plot hyperparameter performance metrics

Usage

plot_hp_performance(dat, param_col, metric_col)

Value

ggplot of hyperparameter performance.

Arguments

dat

dataframe of hyperparameters and performance metric (e.g. from get_hp_performance() or combine_hp_performance())

param_col

hyperparameter to be plotted. must be a column in dat.

metric_col

performance metric. must be a column in dat.

Examples

# plot for a single `run_ml()` call
hp_metrics <- get_hp_performance(otu_mini_bin_results_glmnet$trained_model)
hp_metrics
plot_hp_performance(hp_metrics$dat, lambda, AUC)
if (FALSE) {
# plot for multiple `run_ml()` calls
results <- lapply(seq(100, 102), function(seed) {
  run_ml(otu_small, "glmnet", seed = seed)
})
models <- lapply(results, function(x) x$trained_model)
hp_metrics <- combine_hp_performance(models)
plot_hp_performance(hp_metrics$dat, lambda, AUC)
}
