RESEARCH PROJECTS

  Orthogonal Graph Mining: Designed an algorithm for mining a representative set of maximal graph patterns with each member satisfying pairwise orthogonality constraint.
  Data Mining Template Library: Involved in the design and development of a generic library for frequent pattern mining. The library allows mining customized patterns. The library can be downloaded from SourceForge.net.
 Link Prediction: Involved predicting the likelihood of a link between two entities (in the future) given that they never had a link between them in the past. Explored supervised learning techniques along with Markov chain based techniques to solve the problem. The results were presented at the KDD Challenge.
 Text Categorization Framework: Built a framework that enabled use of various information retrieval and machine learning algorithms at different stages of categorization - feature extraction, cleaning, preprocessing, training and classification. Applied this framework for identifying spam mails.
 Novelty Detection on Video Streams: Used low-level features for detecting inconsistent events in a sequence of video data. Applied unsupervised learning to identify inconsistent events along with habituation theory to model the learning aspect.
 Feature Partitioning for Co-training: Applied feature splitting to the basic co-training setting to improve performance of co-trained classifiers. Explored the idea of extending co-training to k-training for optimal cost-performance ratio.
 Authorship Attribution of Text Documents: Working on developing fault-tolerant sequence mining techniques for capturing stylistic attributes of a text document. The sequences obtained act as features for training a classifier to identify authors.
 Predicting Protein-Protein Interactions: Applying link analysis methods along with graph theoretic and unsupervised learning techniques, for the task of predicting interactions between proteins in an interaction network.
