DDPM to DDIM, Complete Mastery of Diffusion Through Implementation I

This course is a hands-on masterclass that completely conquers the evolution of Diffusion Models through papers and code implementation. You'll learn the core models of generative AI, including DDPM (Denoising Diffusion Probabilistic Model) and DDIM, by studying the paper principles and implementing them directly. We analyze step-by-step the background of each model's emergence, mathematical formulations, network architectures (U-Net, VAE, Transformer), training processes (Noise Schedule, Denoising Step), and the ideas that led to performance improvements. Students will directly code all models using PyTorch, gaining not just paper comprehension but 'practical skills to reproduce and apply' them in real-world scenarios. Additionally, by comparing the differences between models and their developmental flow, you'll clearly understand how they expand and evolve. This course integrates theory, code, and practice into one comprehensive journey, providing researchers, developers, and creators alike with a systematic way to master the evolution of generative models. Beyond simply 'reading' papers, start your experience of 'understanding and recreating' through direct implementation now.

What you will learn!

  • Understand the structure and principles of major diffusion models such as DDPM and DDIM step by step.

  • We directly implement the core ideas presented in each paper through code.

  • Compare the differences between models and experience through experiments how Diffusion-based models started and evolved.

  • Reproduce paper-based models with actual PyTorch code and perform custom image generation experiments.

Course Introduction

This course is a complete hands-on course that teaches you from the fundamental principles of Diffusion models to direct implementation all at once.
You'll understand DDPM (Denoising Diffusion Probabilistic Model), which has become the core of image generation AI, and
DDIM (Denoising Diffusion Implicit Model), which dramatically improved sampling speed,
by following through paper formulas, concepts, code implementation, and experiments.

It doesn't just stop at explaining theory,
but is designed so you can directly see and experience how models "restore from noise" images
by writing actual code.
