Algorithm Unrolling for Massive Access via Deep Neural Network with Theoretical Guarantee
Yandong Shi, Hayoung Choi, Yuanming Shi +1
Massive access is a critical design challenge of Internet of Things (IoT) networks. In this paper, we consider the grant-free uplink transmission of an IoT network with a multiple-…
Any multi-index sequence has an interpolating measure
Hayoung Choi, Seonguk Yoo
R. P. Boas showed that any single-index sequence of real numbers can be represented as (), where…
Large-Scale Beamforming for Massive MIMO via Randomized Sketching
Hayoung Choi, Tao Jiang, Yuanming Shi +2
Massive MIMO system yields significant improvements in spectral and energy efficiency for future wireless communication systems. The regularized zero-forcing (RZF) beamforming is a…
Fast computation of von Neumann entropy for large-scale graphs via quadratic approximations
Hayoung Choi, Jinglian He, Hang Hu +1
The von Neumann graph entropy (VNGE) can be used as a measure of graph complexity, which can be the measure of information divergence and distance between graphs. However, computin…
Geometric Mean of Partial Positive Definite Matrices with Missing Entries
Hayoung Choi, Sejong Kim, Yuanming Shi
In this paper the geometric mean of partial positive definite matrices with missing entries is considered. The weighted geometric mean of two sets of positive matrices is defined,…
An algebraic-geometric approach for linear regression without correspondences
Manolis C. Tsakiris, Liangzu Peng, Aldo Conca +3
Linear regression without correspondences is the problem of performing a linear regression fit to a dataset for which the correspondences between the independent samples and the ob…
