Async Learned User Embeddings for Ads Delivery Optimization
Mingwei Tang, Meng Liu, Hong Li +16
In recommendation systems, high-quality user embeddings can capture subtle preferences, enable precise similarity calculations, and adapt to changing preferences over time to maint…
Electro-Optic Active Metasurfaces for High-Speed Photonic Applications
Mingwei Tang, Ruochong Chen, Yue Cao +6
Metasurfaces are artificially engineered ultrathin nanostructured surfaces, capable of flexibly manipulating light-matter interactions on compact platforms, and thereby of great si…
An Improved Deep Reinforcement Learning Control Strategy for Traction Dual Rectifiers in EMUs
Zhigang Liu, Mingwei Tang, Xiangyu Meng +4
Due to the use of PI-based d q current decoupling in the pulse rectifier of CRH5 high-speed trains, the PI parameters directly affect the traction system's control performance. Lin…
Scalable universal tunable virtual-wavevector spatial frequency shift (TVSFS) super-resolution imaging
Mingwei Tang, Yubing Han, Dehao Ye +8
Developing a chip-based super-resolution imaging technique with large field-of-view (FOV), deep subwavelength resolution, and compatibility for both fluorescent and non-fluorescent…
Large-Aperture All-Solid-State Cascaded Liquid-Crystal Beam Steering for High-Resolution Wide-Field Imaging
Chenxi Liu, Yongxiang Qu, Xiaoxin Wang +10
The paper presents an all‑solid‑state cascaded liquid‑crystal beam‑steering system that electrically redirects sub‑fields of view to extend a high‑resolution narrow‑FOV camera into…
3D orientation super-resolution spatial-frequency-shift microscopy
Xiaowei Liu, Mingwei Tang, Ning Zhou +4
Super-resolution mapping of the 3D orientation of fluorophores reveals the alignment of biological structures where the fluorophores are tightly attached, and thus plays a vital ro…
