Fast Algorithms for Robust PCA via Gradient Descent
Xinyang Yi, Dohyung Park, Yudong Chen +1
We consider the problem of Robust PCA in the fully and partially observed settings. Without corruptions, this is the well-known matrix completion problem. From a statistical standp…

Can One Achieve Multiuser Diversity in Uplink Multi-Cell Networks?
Won-Yong Shin, Dohyung Park, Bang Chul Jung
We introduce a distributed opportunistic scheduling (DOS) strategy, based on two pre-determined thresholds, for uplink -cell networks with time-invariant channel coefficients. E…

Opportunistic Interference Mitigation Achieves Optimal Degrees-of-Freedom in Wireless Multi-cell Uplink Networks
Bang Chul Jung, Dohyung Park, Won-Yong Shin
We introduce an opportunistic interference mitigation (OIM) protocol, where a user scheduling strategy is utilized in -cell uplink networks with time-invariant channel coefficie…
