The Paper That Changed AI Image Generation Forever | Denoising Diffusion in Motion

Описание: How do AI image generators like DALL-E, Stable Diffusion, and Midjourney actually work? It all started with this groundbreaking 2020 paper on Denoising Diffusion Probabilistic Models (DDPM).

🎯 What You'll Learn:
• The fundamental problem with GANs and VAEs
• How diffusion models reverse the destruction of images
• The two-step process: forward diffusion and reverse denoising
• Why DDPM achieved state-of-the-art FID score of 3.17 on CIFAR-10
• The Markov chain structure behind diffusion
• How this paper led to DALL-E, Stable Diffusion, and Midjourney

📊 Key Results:
FID Score: 3.17 (best in 2020)
Dataset: CIFAR-10
Breakthrough: Stable training + high-quality outputs
