On Parameters of Nonlinear Scalar Dynamics from Video: Invariants, Calibration, and Identifiability

Wenjie Wang, Yuanyuan Wang, Zixiang Jiang et al. · 2026

Physical parameter estimation from video aims to recover the parameters of a known family of governing dynamical equations from pixel observations. Existing identifiability theory for this setting has focused on linear time-invariant (LTI) second-order systems, leaving open what can be identified for nonlinear scalar d …

DuraS2ST: Chain-of-Thought and Reinforcement Learning for Duration-Aligned Speech-to-Speech Translation

Yayue Deng, Dingdong Wang, Yuxuan Hu et al. · 2026

Speech-to-speech translation (S2ST) in time-sensitive applications such as video dubbing requires not only semantic fidelity and speaker preservation, but also strict duration consistency to avoid audio-visual misalignment. However, existing S2ST systems largely generate target speech without explicit temporal planning …
