Low rank approximation of positive semi-definite symmetric matrices using Gaussian elimination and volume sampling
Markus Hegland, Frank deHoog
Positive semi-definite matrices commonly occur as normal matrices of least squares problems in statistics or as kernel matrices in machine learning and approximation theory. They a…

Md Shahzamal, Raja Jurdak, Bernard Mans +2
Infectious diseases are still a major global burden for modern society causing 13 million deaths annually. One way to reduce the morbidity and mortality rates from infectious disea…
A Graph Model with Indirect Co-location Links
Md Shahzamal, Raja Jurdak, Bernard Mans +1
Graph models are widely used to analyse diffusion processes embedded in social contacts and to develop applications. A range of graph models are available to replicate the underlyi…
Impact of Indirect Contacts in Emerging Infectious Disease on Social Networks
Md Shahzamal, Raja Jurdak, Bernard Mans +2
Interaction patterns among individuals play vital roles in spreading infectious diseases. Understanding these patterns and integrating their impact in modeling diffusion dynamics o…
