Accelerated and Deep Expectation Maximization for One-Bit MIMO-OFDM Detection
Mingjie Shao, Wing-Kin Ma, Junbin Liu +1
In this paper we study the expectation maximization (EM) technique for one-bit MIMO-OFDM detection (OMOD). Arising from the recent interest in massive MIMO with one-bit analog-to-d…
Extreme Point Pursuit -- Part I: A Framework for Constant Modulus Optimization
Junbin Liu, Ya Liu, Wing-Kin Ma +2
This study develops a framework for a class of constant modulus (CM) optimization problems, which covers binary constraints, discrete phase constraints, semi-orthogonal matrix cons…
Hyperspectral Unmixing Under Endmember Variability: A Variational Inference Framework
Yuening Li, Xiao Fu, Junbin Liu +1
This work proposes a variational inference (VI) framework for hyperspectral unmixing in the presence of endmember variability (HU-EV). An EV-accounted noisy linear mixture model (L…
Personalized Voice Synthesis through Human-in-the-Loop Coordinate Descent
Yusheng Tian, Junbin Liu, Tan Lee
This paper describes a human-in-the-loop approach to personalized voice synthesis in the absence of reference speech data from the target speaker. It is intended to help vocally di…
Extreme Point Pursuit -- Part II: Further Error Bound Analysis and Applications
Junbin Liu, Ya Liu, Wing-Kin Ma +2
In the first part of this study, a convex-constrained penalized formulation was studied for a class of constant modulus (CM) problems. In particular, the error bound techniques wer…
A Scalable and Exact Relaxation for Densest -Subgraph via Error Bounds
Ya Liu, Junbin Liu, Wing-Kin Ma +1
Given an undirected graph and a size parameter , the Densest -Subgraph (DS) problem extracts the subgraph on vertices with the largest number of induced edges. While D…
