On Heterogenous Bridge Monitoring Across Various Structural Changes by Hybridized Unsupervised Learning

Yu Wu, Amirhossein Haydarzadeh, Alireza Entezami, Hassan Sarmadi

Ensuring the long-term integrity and health of bridge structures under diverse structural, environmental, and operational conditions remains a persistent challenge within the structural health monitoring (SHM) community. Although machine learning–aided unsupervised anomaly detect…

Forecasting Dam Displacements with Limited Monitoring Data via Sequential Statistical–Deep Regression Modelling

Yu Wu, Hesam Kiarad, M. Hassani, Hassan Sarmadi, Alireza Entezami

Dam displacement monitoring is imperative to assess the operational status and structural safety of dams under various environmental conditions and operational loads. Although most of the dam structures are instrumented with robust in-situ sensing systems, long-term field monitor…

DSpark: Confidence-Scheduled Speculative Decoding with Semi-Autoregressive Generation

Xin Cheng, Xingkai Yu, Chenze Shao, Jiashi Li, Yunfan Xiong, Yi Qian, et al.

Speculative decoding accelerates Large Language Model (LLM) inference by decoupling draft generation from target verification. While recent parallel drafters efficiently propose long token sequences in a single forward pass, they suffer from rapid acceptance decay due to a lack o…

SIFT: Self-Imagination Fine-Tuning for Physically Plausible Motion in Video Diffusion Models

Ruoyu Wang, Jialun Liu, Huayang Huang, Haibin Huang, Jiepeng Wang, Chi Zhang, et al.

Recent advances in video diffusion models have greatly improved visual fidelity, yet their generated motions often violate physical plausibility. We observe a common kinematic failure, "motion entanglement", the unintended coupling of independent motion sources, such as camera mo…
