Denoising Diffusion Probabilistic Models | DDPM Explained

In this video, I get into diffusion models and specifically we look into denoising diffusion probabilistic models (DDPM). I try to provide a comprehensive guide to understanding entire maths behind it and training diffusion models ( denoising diffusion probabilistic models ). 🔍 Video Highlights: 1. Overview of Diffusion Models: We first look at the code idea in diffusion models 2. DDPM Demystified: We break down entire math in Denoising Diffusion Probabilistic Models in order to gain a deep understanding of the algorithms driving these innovative models. 3. Training and Sampling in Diffusion Models: Finally we look step-by-step on how these are trained and how one can sample images in Denoising Diffusion Probabilistic Models Timestamps 00:00 Introduction 00:25 Basic Idea of Diffusion Models 02:23 Why call this Diffusion Models 05:24 Transition function in Denoising Diffusion Probabilistic Models - DDPM 07:28 Distribution at end of forward Diffusion Process 10:17 Noise Schedule in Diffusion Models 11:36 Recursion to get from original image to noisy image 13:40 Reverse Process in Diffusion Models 14:40 Variational Lower Bound in Denoising Diffusion Probabilistic Models - DDPM 17:02 Simplifying the Likelihood for Diffusion Models 19:08 Ground Truth Denoising Distribution 22:31 Loss as Original Image Prediction 24:10 Loss as Noise Prediction 26:26 Training of DDPM - Denoising Diffusion Probabilistic Models 27:17 Sampling in DDPM - Denoising Diffusion Probabilistic Models 28:30 Why create this video on Diffusion Models 29:10 Thank You 🔔 Subscribe : https://tinyurl.com/exai-channel-link Useful Resources Paper Link - https://tinyurl.com/exai-ddpm-paper Jeremy Howard - https://www.youtube.com/playlist?list=PLfYUBJiXbdtRUvTUYpLdfHHp9a58nWVXP Calvin Luo - https://calvinyluo.com/2022/08/26/diffusion-tutorial.html Joseph Rocca - https://towardsdatascience.com/understanding-diffusion-probabilistic-models-dpms-1940329d6048 Outlier - https://www.youtube.com/watch?v=HoKDTa5jHvg&ab_channel=Outlier Lilian Weng - https://lilianweng.github.io/posts/2021-07-11-diffusion-models Ayan Das - https://ayandas.me/blog-tut/2021/12/04/diffusion-prob-models.html Jonathan Goodman - https://math.nyu.edu/~goodman/teaching/StochCalc2013/notes/Week7.pdf 📌 Keywords: #DiffusionModels #DDPMExplained Background Track - Fruits of Life by Jimena Contreras Email - [email protected]
