Unifying Distributional Training for One-Step Visual Generation

A unified theoretical framework is introduced that separates distribution modeling from matching discrepancy and connects global objectives to pointwise feature updates through Wasserstein gradient flow and motivates MGFlow, which models feature distributions with Gaussian mixtures at an adjustable granularity between...

From Scores to Samples: Elastic Forcing for Autoregressive Video Generation

This framework minimizes maximum mean discrepancy in frozen self-supervised video representation spaces in frozen self-supervised video representation spaces, using a hybrid Nystr\"om--Monte Carlo estimator to balance approximation bias and sampling variance.

InteracVid: Building a Real Interactive Audio-Visual Response Dataset from Live-Chat Videos

InteracVid is introduced, the first open-source large-scale dataset that addresses this missing supervision, so that every sample couples a preceding audio-visual context and an external stimulus with the realinteractive response that follows.
