[📄preprint] Diffusion models 🤝 MCMC !

Diffusion model samplers are biased due to discretisation

💡The fix: Metropolis-type adjustment on corrector steps
❗️Challenge: no access to the density ratio, only the score
🔑Insight: the score (and some maths) is all you need...

vqvae刚出来的时候，就觉得想法很棒。现在2代出来，效果更好了，过几天再把这个2代实现鸟

VQVAE-2 finally out!

Powerful autoregressive models in a hierarchical compressed latent space. No modes were collapsed in the creation of these samples ;)

オタクというか、物事にマニアックな人というのは、興味の対象をこんな風に掘って行くのではないかと思っていて。最初はたしかに興味分野を掘り始めるのだけど、掘ってくうちに興味の対象外分野まで否応無く掘り返してしまう、掘り返さざるを得なくなるというイメージ。
