A generalized framework for mining spatio-temporal patterns in scientific data (2005)

Hui Yang, Srinivasan Parthasarathy, Sameep Mehta

In this paper, we present a general framework to discover spatial associations and spatio-temporal episodes for scientific datasets. In contrast to previous work in this area, features are modeled as...

Dynamic classification of defect structures in molecular dynamics simulation data (2005)

Sameep Mehta, Steve Barr, Alex Choy, Hui Yang, Srinivasan Parthasarathy, Raghu Machiraju, ...

In this application paper we explore techniques to classify anomalous structures (defects) in data generated from Molecular Dynamics (MD) simulations of Silicon (Si) atom systems. These systems are...

Discovering spatial relationships between approximately equivalent patterns (2004)

Hui Yang, Keith Marsolo, Srinivasan Parthasarathy, Sameep Mehta

We present a method for finding relationships between approximate patterns in contact maps. We examine contact maps generated from protein data in order to discover spatial relationships among the...
