原文高亮摘录
“stochastic gradient Langevin dynamics injects Gaussian noise into the parameter updates to avoid collapses into local minima.”
Whisper 随想笔记
Huh, but doesn't the noise mess up the final accuracy sometimes?

So it's like adding a little randomness to not get stuck, makes sense.

“Diffusion models are inspired by non-equilibrium thermodynamics.”
Whisper 随想笔记
But how is that different from just adding noise, though?

Whisper 随想笔记
Makes sense why my physics background finally pays off.

So basically they're just fancy thermodynamics, huh.
