[Review] Diffusion Models 2 - 작성 중

Diffusion Model이 sample quality 측면에 있어서 높은 fidelity를 자랑한다면, density estimation은 어떨까? log-likelihood를 최소화하도록 Diffusion Model에 약간의 변형을 줘 본, 아래 2개의 논문을 리뷰해보자.

1. Song et al. (2021). Maximum likelihood training of score-based diffusion models.
2. Kingma et al. (2021). Variational diffusion models.

1. Likelihood Weighting

2. VDM
