Undergraduate Projects:
I pursued an melange of projects in my undergraduate days. Select summaries follow:
  • Statistical models of Language Evolution in Multiple agent communities (pdf) (abstract)
    Advisor: Dr. Harish Karnick, IIT Kanpur
    • Analysis of social interaction and language learning models, for different community graphs, extending a well known syntactic model of language
    • Analyzed language mingling and divergence in communities by stochastically coupling agent based approaches with population dynamics
    • Explored role of social topologies in shaping the course of linguistic evolution and language divergence
  • Reinforcement Learning based Autoguider for Astrophotography
     (pdf) (abstract)                                                        
    Advisors: Dr. Bernhard Scholkopf and Dr. Jan Peters, Dept of Statistical Inference, Max Planck Institute Tubingen
    • Designed and implemented a two variable Q-learning type formulation for autoguiding a Mach GTO German Equitorial Mount for star-tracking and astrophotography
    • Formulated problem as a continuous Markov Decision Process with agent `actions' corresponding to motor movement durations, and fine tuned simultaneous independent learners for Right Ascension and Declination axes
    • Extensive indoor simulations using convolutions on laser point source for robust star detection heuristics

  • Electronic Calculus Tutor for Undergraduate Math                                                                                                 
    Advisors: Prof. Larissa Fradkin, Victor Zernov, South Bank University, London
    • Decision-tree based differentiation tutor in JAVA for differential calculus: aimed to teach undergraduate level Math to students with learning disabilities
    • Developed a non-deterministic question generator, enabling a larger range of practice questions; expanding on existing MVC design-pattern

  • A GO based clustering for prognosis and inference from microarray data. (pdf) (poster) (abstract) (extended abstract)
    • Extending the statistical approach using a knowledge infusion from the Gene Ontology, we propose a method that expresses a biological snapshot in terms of gene functions, and directly yields some biological understanding
    • Prognostic predictions for two B-cell lymphomas corroborate with medical literature
    • Poster presented at Asia Pacific Bioinformatics Conference (APBC), 2010
    • A Content-based Similarity Search for Monophonic Melodies. (pdf) (poster) (abstract)
      • Searching for the most similar melodies for an input query (fom a MIDI keyboard) from a musical database. We use clustering on global features followed by use of individual feature matching using Transportation distances
      • Poster presented at IBM I-CARE Workshop, 2009 held in New Delhi
    • Enhancing click-rates of online Advertisements. (pdf)
      • Local clustering for rare class analysis and SVM for classification to identify patterns that would lead to higher click rates of online advertisements
      • Adjudged best solution to problem proposed by Komli (www.komli.com)
    • Credit Card Fraud Detection: UCSD Data Mining Contest, June - July 2009
      • Detected 85.7% of fraudulent transactions (lift of 4.286 at 20% ) using J48 Decision trees and extensive feature preprocessing
      • Best Indian team at UCSD 2009 Data Mining Contest
    • Amateur attempts on the Physiological Data Modeling Problem.
      • Comparative analysis of classification algorithms on the Physiological Modeling Dataset: emphasis on the performance of Support Vector Machines and use of a semi-supervised approach in the final algorithm
    • A Color-based Indexing for Image Similarity Searching. (pdf) (abstract)
