Covariance-Aware MM-PGD for Mixed Near-/Far-Field Activity Detection

Xinjue Wang, Zhi-Yong Wang, Sergiy A. Vorobyov +3

Grant-free activity detection with mixed near-field (NF) and far-field (FF) devices is an important problem that can be addressed via covariance-based detectors. The difficulty is…

Finer Parameter Steps for Low-Rank PEFT: A Controlled Study with CP Tensor Adapters

Xinjue Wang, Xiuheng Wang, Yejun Zhang +3

Low-rank adapters are usually compared by sweeping a small set of ranks, but the rank also fixes the resolution of the parameter budget. For a OPT attention proj…
