Federated Learning with Lossy Distributed Source Coding: Analysis and Optimization
Huiyuan Yang, Tian Ding, Xiaojun Yuan
Recently, federated learning (FL), which replaces data sharing with model sharing, has emerged as an efficient and privacy-friendly machine learning (ML) paradigm. One of the main…
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…
The Global Landscape of Neural Networks: An Overview
Ruoyu Sun, Dawei Li, Shiyu Liang +2
One of the major concerns for neural network training is that the non-convexity of the associated loss functions may cause bad landscape. The recent success of neural networks sugg…
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…
On the Benefit of Width for Neural Networks: Disappearance of Bad Basins
Dawei Li, Tian Ding, Ruoyu Sun
Wide networks are often believed to have a nice optimization landscape, but what rigorous results can we prove? To understand the benefit of width, it is important to identify the…
Sparsity Learning Based Multiuser Detection in Grant-Free Massive-Device Multiple Access
Tian Ding, Xiaojun Yuan, Soung Chang Liew
In this work, we study the multiuser detection (MUD) problem for a grant-free massive-device multiple access (MaDMA) system, where a large number of single-antenna user devices tra…
On the Degrees of Freedom of the Symmetric Multi-Relay MIMO Y Channel
Tian Ding, Xiaojun Yuan, Soung Chang Liew
In this paper, we study the degrees of freedom (DoF) of the symmetric multi-relay multiple-input multiple-output (MIMO) Y channel, where three user nodes, each with M antennas, com…
