Learning the integral of a diffusion model – Sander Dieleman

0 CommentsEntertainment

🚀 Discover this insightful post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: Sampling from a diffusion model is an iterative process: at each step, the denoiser estimates the tangent direction to a path through input space. We move along this path by repeatedly taking small steps in this direction, effectively calculating an integral across noise levels. This gradually transforms samples from a simple noise distribution into samples from a target distribution, and traces out the path that connects them. Can we train neural networks to directly predict this integral instead, in order to speed up sampling? Yes…
