Description

Plot chosen metric in group. Notice how models are treating different subgroups. Compare models both in fairness metrics and in performance. Parity loss can be enabled when creating group_metric object.

Usage

# S3 method for group_metric
plot(x, ...)

Value

list of ggplot2 objects

Arguments

x

object of class group_metric

...

other group_metric objects and other parameters

Examples

data("german")

y_numeric <- as.numeric(german$Risk) - 1

lm_model <- glm(Risk ~ .,
  data = german,
  family = binomial(link = "logit")
)


explainer_lm <- DALEX::explain(lm_model, data = german[, -1], y = y_numeric)

fobject <- fairness_check(explainer_lm,
  protected = german$Sex,
  privileged = "male"
)

gm <- group_metric(fobject, "TPR", "f1", parity_loss = TRUE)
plot(gm)
# \donttest{

rf_model <- ranger::ranger(Risk ~ .,
  data = german,
  probability = TRUE,
  num.trees = 200
)

explainer_rf <- DALEX::explain(rf_model, data = german[, -1], y = y_numeric)

fobject <- fairness_check(explainer_rf, fobject)

gm <- group_metric(fobject, "TPR", "f1", parity_loss = TRUE)

plot(gm)
