RADRadar: Range-Angle-Doppler Feature Cube Reconstruction for Radar Scene Perception

Jiawei Qiao, Shuaifeng Zhi, Dewen Hu, Weidong Jiang

RA-L 2025

Compared to cameras and lidars, millimeter-wave radar's capability to operate under all-weather, all-day conditions makes it indispensable in autonomous driving. The radar cube, comprising range (R), azimuth (A), and Doppler velocity (D) dimensions, serves as an effective data representation due to

Neural Frailty Machine: Beyond proportional hazard assumption in neural survival regressions

Ruofan Wu, Jiawei Qiao, Mingzhe Wu, Wen Yu, Ming Zheng, Tengfei LIU +2

NeurIPS 2023poster

We present neural frailty machine (NFM), a powerful and flexible neural modeling framework for survival regressions. The NFM framework utilizes the classical idea of multiplicative frailty in survival analysis as a principled way of extending the proportional hazard assumption, at the same time bein…
