ORNL Supports Vatsavai’s Research on Big Data

Dr. Ranga Raju Vatsavai, associate professor of computer science at NC State University, has been awarded $49,021 by the Oak Ridge National Laboratory (ORNL) to support his research proposal entitled “Architecture Driven Optimization Approaches for Pattern Discovery from Big Data.”  The award will support the work of Vatsavai’s graduate student, Seokyong Hong.
The award will run from October 15, 2014 to September 30, 2015. 
Abstract – Pattern discovery and predictive modeling from seemingly related “Big Data” represented as massive, ad-hoc, heterogeneous networks (e.g., extremely large graphs with complex, possibly unknown structure) is an outstanding problem in many application domains. To address this problem, we will be designing graph-mining algorithms capable of: (i) discovering relationship-patterns from such data and (ii) use those discovered patterns as features for classification and predictive modeling. In particular, we will develop, implement, and demonstrate novel, automated and scalable graph-pattern discovery algorithms on two different architectures: (1) Crays™ Urika, and (2) Hadoop based Cluster. The research will bring forth the advantages and disadvantages these two different architectures and shows possible optimization approaches for pattern discovery from big data.
