Semi-Supervised Hyperbolic Hierarchical Clustering with Set-Level Structural Priors

Junjing Zheng, Xinyu Zhang, Xiangfeng Qiu +2

Semi-supervised hierarchical clustering aims to learn a tree structure consistent with data patterns and user-provided supervision. Supervision is usually given as leaf-level relat…

Worst-Case Riemannian Optimization with Uncertain Target Steering Vector for Slow-Time Transmit Sequence of Cognitive Radar

Xinyu Zhang, Weidong Jiang, Xiangfeng Qiu +1

Optimization of slow-time transmit sequence endows cognitive radar with the ability to suppress strong clutter in the range-Doppler domain. However, in practice, inaccurate target…
