letter-night.tistory.com 밤에 쓰는 편지 Understanding Diffusion Probabilistic Models (DPMs) Introduction Modelling complex probability distributions is a central problem in machine learning. If this problem can appear under different shapes, one of the most common setting is the following: given a complex probability distribution only described by some available samples, how can one generates a new sam What is a diffusion process? As suggested by their name, diffusion probabilistic models are related in some way to diffusion processes. So let’s start by the very beginning and see what a diffusion process is and what are its properties. Of course, as it is not the core subject of this post, we will have to make some simplifica Intuition of diffusion models With some well chosen coefficients, a diffusion process has the effect to progressively destroy any relevant information. Indeed, a diffusion with a “shrinking” drift coefficient (|a|<1) and a non-null diffusion coefficient will progressively turn data from any complex distribution into data from a Mathematics of diffusion models Despite both continuous and discrete time formulation of diffusion models exist, we will focus in this post on the later. It means we will assume that the forward diffusion process and the backward reverse process have been discretised into a finite number T of steps. Notice that for both the forwar Diffusion models in practice So far we have defined a forward process q acting as our (discretised) diffusion process that progressively destroy information as well as a backward process p_θ modelling the reverse process to be learned and supposed to progressively restore the information We have then seen that training our reve Takeaways The main takeways of this article are: generative processes all aim at the same goal that consists in defining a function that takes data from a simple distribution and convert in into data from a complex distribution learning a function (represented by a neural network) that takes some gaussian noi 59 Modelling complex probability distributions is a central problem in machine learning.
