Regulirani Gaussov model smjese

Regulirani Gaussov model smjese (GMM) dodaje malu pozitivnu konstantu na dijagonalu svake kovarijacijske matrice komponente tijekom algoritma očekivanja-maksimalizacije, čime se sprječavaju singularne ili gotovo singularne matrice koje uzrokuju numeričke pogreške kada su podaci rijetki, visokodimenzionalni ili sadrže gotovo duplicirane opservacije.
