RAG & Retrieval
Flow Matching
A way to train generative models by learning a vector field that carries samples from simple noise to real data along a chosen probability path.
In depth
A way to train generative models by learning a vector field that carries samples from simple noise to real data along a chosen probability path. To generate, you integrate that field with an ODE solver. Lipman et al. introduced it in 2022: training needs no simulation, diffusion becomes one special case of path, and straight optimal-transport paths trained and sampled faster than diffusion paths. Many recent image, video and audio generators are trained with flow matching or the closely related rectified flow.
