A Good Score Does not Lead to A Good Generative Model

1 code implementation10 Jan 2024 Sixu Li, Shi Chen, Qin Li

In particular, it has been shown that SGMs can generate samples from a distribution that is close to the ground-truth if the underlying score function is learned well, suggesting the success of SGM as a generative model.
