ViRDM: Taming Representation Distribution Matching for Few-Step Causal Video Generation

Zichong Meng, Chongjian Ge, Chun-Hao P. Huang et al. · 2026

Few-step autoregressive (AR) video diffusion enables low-latency streaming generation, but existing post-training methods predominantly rely on Distribution Matching Distillation (DMD), requiring both a large pretrained teacher and an online critic to estimate distributional discrepancies through diffusion scores. In t …

LYRIC: Language-Driven Physics-Based Character Control for Contact-Rich Whole-Body Object Interaction

Zeyu Han, Zichong Meng, Julian Tanke et al. · 2026

We present LYRIC, a generative flow-matching controller for language-driven physics-based contact-rich interaction control, that enables simulated characters to perform contact-rich whole-body object interactions from a free-form language instruction and a sparse terminal object goal. To obtain reliable expert trajecto …
