Research Experience:

Internships:

Jan 2013- March 2013
Research Assistant, Dalhousie University, Halifax, Canada
  • Evaluation of topic extraction (word clustering) algorithms
  • Developed a topic extraction algorithm that allows simple user interaction.

May 2012-Jul 2012: Research Assistant, Dalhousie University, Halifax, Canada
Text mining using one-mode projection graphs
  • Developed an algorithm for graph based clustering of document using thresholding on one-mode projection graph that can be used along with other clustering algorithms like modularity optimization.
  • Developed a simple graph based topic extraction algorithm and proposed five evaluation metrics to evaluate different aspects of topics/word clusters using the labels associated with documents.
  • Developed an algorithm for multi-label classification using neighbors in the one-mode projection graph of documents.
May 2011-Jul 2011: Summer Intern, Central Electronics Engineering Research Institute (CEERI), Pilani, India
  • Improvement of the SVM Algorithm for Emotion Recognition: Generalized an earlier work on training linear SVM along with Gabor filters for image classification without information loss to non-linear SVMs.
  • Gestalt Grouping in Computer Vision: Studied the application of psychology of Gestalt grouping in Computer Vision.
May 2010-Jul 2010:Summer Intern, Indian Institute of Technology, Kharagpur, India
Modeling complex networks
  • Twitter network: Developed the analytical framework to model the Twitter network by formulating and solving network growth model, and proposed a utility function to assess soft cut-off.
  • Study of evolving real life bipartite networks (collaboration networks): Studied the degree-distribution of projection graphs of a bipartite networks with one fixed and one infinitely growing set, by forming an analogy with Polya’s urn scheme.
