TL;DR
本文研究通过score estimation进行diffusion models的学习,探讨gradient descent和EM算法在学习Gaussian mixture models方面的效率,证明了其在特定情况下达到高效的效果。
Abstract
Recent works have shown that
diffusion models
can learn essentially any distribution provided one can perform
score estimation
. Yet it remains poorly understood under what settings
