Beamforming Design with Fast Convergence for IRS-Aided Full-Duplex Communication
Hong Shen, Tian Ding, Wei Xu +1
We study the beamforming optimization for an intelligent reflecting surface (IRS)-aided full-duplex (FD) communication system in this letter. Specifically, we maximize the sum rate…

Sub-Optimal Local Minima Exist for Neural Networks with Almost All Non-Linear Activations
Tian Ding, Dawei Li, Ruoyu Sun
Does over-parameterization eliminate sub-optimal local minima for neural networks? An affirmative answer was given by a classical result in [59] for 1-hidden-layer wide neural netw…
