Bayesiansk Gaussisk Blanding (Bayesian Gaussian Mixture Model)
Den Bayesianske Gaussiske Blanding (Bayesian Gaussian Mixture Model) placerer prior-fordelinger over alle blandingsparametre og infererer deres posterior-fordelinger – typisk via Variational Bayes eller MCMC – snarere end at tilpasse faste punktestimater. Dette giver principiel usikkerhedskvantificering, automatisk valg af det effektive antal komponenter og modstandsdygtighed over for overfitting af små datasæt.
