Mean Velocity Matching: Rethinking Generative Dynamics in Diffusion Models

This work studies prediction parameterization for stochastic generative dynamics in diffusion models. Existing velocity-based generative models provide the simplicity of learning a single transport field, but their standard formulation is deterministic, whereas stochastic extensions generally require additional score i...

Scattering Center Prior-Guided Diffusion for Unknown-Azimuth SAR Image Generation

Generating synthetic aperture radar (SAR) images at unknown azimuth angles under limited sample conditions remains a challenging task, since target scattering characteristics vary significantly with observation angle and are difficult to model effectively using only image-domain priors. To address this issue, this pape...

A Unified Backbone--Expert Framework with Relation-Token and Residual--Classifier Interfaces for Automatic Modulation Recognition

A unified backbone-expert framework with a common convolutional state-space backbone and two specialized interfaces for automatic modulation recognition, confirming the benefit of expert-interface decoupling over one-size-fits-all architectures.
