3. 简化 add noise 过程。 48:24
4. 计算一个 lower bound。54:29
5. Words is discrete, noise should be added to Word embedding. Or adding other noise not Gaussion distribution, such as [MASK]. 01:34:53
6. Diffusion model is taking advantage of the autoregressive method and applys it to non-autoregressive model. 01:43:08
