Regularizētā loģistikā regresija

Regularizētā loģistikā regresija paplašina standarta loģistikā regresiju, pievienojot L1 (lasso), L2 (ridge) vai elastīgā tīkla (elastic net) sodu log-liklihoodam, samazinot koeficientus uz nulli un novēršot pārāk lielu pielāgošanos (overfitting). Tā ir noklusējuma izvēle binārai vai multinomiālai klasifikācijai, kad nepieciešami interpretējami, reti (sparse) vai stabili koeficientu novērtējumi augstas dimensijas vai kolineāros pazīmju (feature) telpās.
