- aif360.sklearn.metrics.smoothed_selection_rate(y_true, y_pred, *, concentration=1.0, pos_label=1, sample_weight=None)[source]
Compute the smoothed selection rate, \(\frac{TP + FP + \alpha}{P + N + |R_Y|\alpha}\).
- Parameters:
y_true (array-like) – Ground truth (correct) target values. Ignored.
y_pred (array-like) – Estimated targets as returned by a classifier.
concentration (scalar) – Dirichlet smoothing concentration parameter \(|R_Y|\alpha\) (must be non-negative).
pos_label (scalar, optional) – The label of the positive class.
sample_weight (array-like, optional) – Sample weights.
- Returns:
float – Smoothed selection rate.
