denoising-diffusion-probabilistic-model-toy-project's Introduction

Denoising Diffusion Probabilistic Model toy project

This repository contains an implementation of Diffusion model from "Denoising Diffusion Probabilistic Models" paper : https://arxiv.org/abs/2006.11239*

Instead of applying diffusion model on images, we apply it on differents 2d data points distibutions. Distributions are created from black and white images stored in images/ by image_to_toy_dataset() from src directory.

denoising-diffusion-probabilistic-model-toy-project's Issues

Cannot reproduce the results

Hi,

This project is beneficial for me as a beginner of the DDPM. However, I cannot reproduce the result without any changes. Could you provide the requirements so that I can match the packages used in the project? Thanks.

Figure 1. Cannot generate the circle image using the original code.

Figure 2. Therefore, I produce a new circle in this way.

Figure 3. Using the above new circle as data, the results are bad.

Best,
