Second year Ph.D. Student School of Computing,

I finished my M.Tech. in I.T. from Indian Institute of Technology - Kharagpur in 2006. I finished by B.E. from Shri U.V. Patel College of Enginerring-Gujarat in 2002. I worked as a lecturer at Nirma University from 2002 to 2004. My current supervisior is Prof. Wynne Hsu and Lee Mong Lee. My M.Tech. supervisor was Prof. Arobinda Gupta.

Interest

Time is important, isn't it? My current research interest is

Temporal pattern mining: Given a Time series data, Sequence data and or Interval-based event sequences, design an efficient data mining algorithm to discover the frequent pattern efficiently. The discover pattern can be used for performing correlation analysis or designing a classifier based on frequent pattern. (IEMiner & IEClassifier)
Time Series Correlation analysis
Time series Indexing for similarity search
Scaling all pair similarity search
Multi-dimension star joins

In Progress

Multi-dimensions Multi-tables similarity join
Update : VAST Challenge 2008 - Data mining approach for suspicious detection
