A review of distributed algorithms for principal component analysis

SX Wu, HT Wai, L Li, A Scaglione - Proceedings of the IEEE, 2018‏ - ieeexplore.ieee.org
Principal component analysis (PCA) is a fundamental primitive of many data analysis, array
processing, and machine learning methods. In applications where extremely large arrays of …

Distributed estimation of principal eigenspaces

J Fan, D Wang, K Wang, Z Zhu - Annals of statistics, 2019‏ - pmc.ncbi.nlm.nih.gov
Principal component analysis (PCA) is fundamental to statistical machine learning. It extracts
latent principal factors that contribute to the most variation of the data. When data are stored …

Low rank approximation with entrywise l1-norm error

Z Song, DP Woodruff, P Zhong - Proceedings of the 49th Annual ACM …, 2017‏ - dl.acm.org
We study the ℓ1-low rank approximation problem, where for a given nxd matrix A and
approximation factor α≤ 1, the goal is to output a rank-k matrix  for which‖ A-Â‖ 1≤ α …

In-network PCA and anomaly detection

L Huang, XL Nguyen, M Garofalakis… - Advances in neural …, 2006‏ - proceedings.neurips.cc
We consider the problem of network anomaly detection in large distributed systems. In this

Relative error tensor low rank approximation

Z Song, DP Woodruff, P Zhong - Proceedings of the Thirtieth Annual ACM …, 2019‏ - SIAM
We consider relative error low rank approximation of tensors with respect to the Frobenius
norm. Namely, given an order-q tensor A∊ ℝ∏ i= 1 q ni, output a rank-k tensor B for which …

A survey of emerging trend detection in textual data mining

A Kontostathis, LM Galitsky, WM Pottenger… - Survey of text mining …, 2004‏ - Springer
What is an emerging trend? An emerging trend is a topic area that is growing in interest and
utility over time. For example, Extensible Markup Language (XML) emerged as a trend in the …

Optimal principal component analysis in distributed and streaming models

C Boutsidis, DP Woodruff, P Zhong - … of the forty-eighth annual ACM …, 2016‏ - dl.acm.org
This paper studies the Principal Component Analysis (PCA) problem in the distributed and
streaming models of computation. Given a matrix A∈ R m× n, a rank parameter k< rank (A) …

Improved distributed principal component analysis

Y Liang, MFF Balcan… - Advances in neural …, 2014‏ - proceedings.neurips.cc
We study the distributed computing setting in which there are multiple servers, each holding
a set of points, who wish to compute functions on the union of their point sets. A key task in …
