Dynamics as Code: On Model Compression via Dynamic System

Fan Gao, Wei Su, Juntong Fan et al. · 2026

The escalating size of pretrained neural networks has rendered model compression a prerequisite for deployment under stringent memory and compute constraints. With the irrational winding as an example, earlier work introduced a dynamic system (DS) paradigm that reconceptualizes compression as compact weight representat …

WorldSonus: Bringing Sound to Worlds

Pengjun Fang, Jingyi Fa, Kam Man Wu et al. · 2026

Recent advances in world models have enabled increasingly realistic visual synthesis. However, these generated environments remain largely silent. Bringing sound to world models poses three core challenges: real-time generation to keep pace with interactive video streams, interactive control to respond to mid-stream so …

HelixWorld: A Real-time Interactive Audio-Visual World Model

Lei Ke, Jiahao Pan, Zeyue Tian et al. · 2026

World simulation is inherently multisensory, demanding synchronized visual and acoustic dynamics in real time. Yet prevailing interactive world models remain strictly silent, focusing exclusively on visual rendering and control while overlooking the acoustic dimension. We present HelixWorld, a real-time interactive aud …
