The core innovation of fixed-point score matching is replacing the denoising score identity in stochastic interpolation with a target score identity, substituting samples generated by the current model for the true target samples, thereby shifting the expectation from computation under the target distribution to computation under the model distribution.

UnverifiedThe iterative loop of fixed-point score matching is: generate terminal samples from the current model and store them in a replay buffer, compute the energy gradient at these samples, then supervise learning with standard score matching and flow matching losses, and repeat after updating the model.75% similarUnverifiedIn diffusion models, the score function is used to describe the log gradient of the data distribution and is trained via denoising score matching.71% similarVerifiedThe idea of flow matching is to learn a time-dependent vector field v_t(x) such that the ordinary differential equation driven by this vector field can transport a simple reference distribution to the target data distribution.71% similarUnverifiedMainstream generative models such as diffusion models and flow matching models are essentially probabilistic generators that produce new samples by sampling from data distributions.70% similarUnverifiedFlow matching models generate images by learning a continuous probability flow (ODE trajectory) from the noise distribution to the data distribution, and are generally more stable to train and require fewer inference steps.70% similar
