Plocha pod krivkou (AUC)

Plocha pod krivkou (AUC) je základná metrika v strojovom učení, ktorá sa používa na hodnotenie výkonnosti binárnych klasifikačných modelov. Kvantifikuje celkovú schopnosť modelu rozlišovať medzi pozitívnymi a negatívnymi triedami výpočtom plochy pod krivkou ROC (Receiver Operating Characteristic).

ROC krivka

ROC krivka (Receiver Operating Characteristic) je grafické zobrazenie používané na hodnotenie výkonu binárneho klasifikačného systému pri meniacom sa prahu diskriminácie. Pochádza z teórie detekcie signálov z obdobia druhej svetovej vojny a dnes je nevyhnutná v strojovom učení, medicíne a AI pri hodnotení modelov.
