Keinert, F. & N. Vaswani
Recursive Robust Principal Components Analysis (PCA)
National Science Foundation
2011 - 2014

Given an overcomplete set of vectors (the dictionary) and a given vector (the data set), the goal of Principal Components Analysis is to find the sparsest linear combination of dictionary elements which approximately represents the data set. Essentially, this is data compression.

This grant aims to develop new algorithms for the case where there is a sequence of data sets which change slowly over time, such as frames in a video. The correlation between frames will be used to both remove sparse outliers (robustness) and reduce computation time by using the results from previous steps (recursiveness).  Key potential applications include automatic foreground extraction from similar looking backgrounds in video; sensor networks based detection and tracking of abnormal events such as forest fires; online detection of brain activation patterns from functional MRI sequences; or speech/audio extraction from large but correlated background noise.

Poon, Y.T. with N.S Sze of Hong Kong Polytechnic University
Entanglement in Quantum Information Science
Hong Kong Research Grants Council
2010 - 2014

The aim of this project is to study problems related to quantum entanglement, explore new separability criteria as well as improve and generalize some of those existing separability criteria. The investigators will collaborate with experimentalists and practitioners so that the research team will focus on important and useful problems. The long term goal is to provide simple, practical, and computational tools to experimentalists and develop new mathematical techniques with wide applicability in quantum entanglement.
