VDOT++: Unified Few-Step Video Generation via Unbalanced Optimal Transport Distillation

Video creation spans text-to-video (T2V), image-to-video (I2V), and condition-based generation, yet video diffusion models remain costly because they repeatedly evaluate large backbones during sampling. Distribution matching distillation (DMD) reduces this cost, but its reverse Kullback--Leibler (KL) objective can prov...

It is shown that one-layer transformers with an argmax classification head behave identically to a one-nearest-neighbor classifier in the multiclass setting by leveraging the simplex encoding.
