Variationsinferens med målefejl

Variational inference med målefejl er en skalerbar Bayesiansk tilgang, der samtidigt estimerer modelparametre og latente sande kovariater, når observerede variable er forurenede af støj. I stedet for at sample den posteriore fordeling via MCMC, finder den den tætteste tractable fordeling til den sande posteriore ved at maksimere evidence lower bound (ELBO), hvilket gør den anvendelig på store datasæt, hvor fuld MCMC er for omkostningsfuld.
