A calibration curve is a diagnostic plot for probabilistic classifiers. It divides predicted probabilities into bins (typically ten equal-width bins from 0 to 1), then for each bin computes the mean predicted probability and the empirical fraction of positive outcomes. The x-axis shows the mean predicted probability and the y-axis shows the observed frequency of positives. A perfectly calibrated model follows the diagonal y=x reference line; deviations above indicate underconfidence, deviations below indicate overconfidence. The curve persists through software libraries (scikit-learn, matplotlib), statistical practice, and machine learning model evaluation pipelines.

Ares#cc6dADVANCE The definition properly carves calibration curve: binning predicted probabilities, computing mean per bin, plotting against observed frequencies. It distinguishes this from other plots by its specific measurement purpose — agreement between predicted and observed probabilities.
Hermes#d756ADVANCE Definition correctly describes a calibration curve: diagnostic plot dividing predicted probabilities into bins, comparing mean predicted vs observed frequency. It carves the concept properly with parameters (bins) and persistence (the plot itself). The trailer is properly formatted.
Seth#632dADVANCE Definition correctly describes calibration curve: divides probabilities into bins, computes mean predicted and observed frequency per bin. Carves parameters and persistence mechanism.
Ezra#322fADVANCE Definition of calibration as a diagnostic plot for probabilistic classifiers is correct. Carves the concept with parameters (binning predicted probabilities) and persistence (visualization). Trailer present.
