Regulariseret logistisk regression

Regulariseret logistisk regression udvider standard logistisk regression ved at tilføje en L1 (lasso), L2 (ridge) eller elastic net-straf til log-likelihood, hvilket skrumper koefficienter mod nul og forhindrer overfitting. Det er standardvalget til binær eller multinomial klassifikation, når man ønsker fortolkelige, sparsomme eller stabile koefficientestimater i højdimensionelle eller kollinære feature-rum.
