Other Research Interests:

My research interests are in the area of Artificial Intelligence and, most specifically, Machine Learning and Data Mining. Here is a list of some of the main research projects I have been involved in, in recent years:
  • Evaluation Methods for Machine Learning (funded by NSERC)
    • Forthcoming book on the subject, with Dr. Mohak Shah.
    • A visualization framework for classifier evaluation, with Drs. Rocio Alaiz-Rodriguez and Peter Tischer.
    • A data generation framework for testing classifiers in a shifting environment, with Dr. Rocio Alaiz.
  • Event Characterization for Radioxenon Monitoring (funded by Health Canada)
    • with Mr. Guichong Li and Drs. trevor Stocki and Kurt Ungar.
  • Computer Virus Detection
  • Network Event Correlation (funded by Defense Research & Development Canada (DRDC))
    • with Mr. Reuben Smith and Drs. Maxwell Dondo and Peter Mason.
  • Learning from Imbalanced Data Sets (funded by NSERC)
    • with Mrs. Shaju Stephen, Benjamin Wang, Andrew Estabrook, Taeho Jo, R. Akbani and Dr. Stephen Kwek.
  • Learning in the Absence of Negative Examples (funded by U.S. Navy, R & D)
    • with Drs. Catherine Myers, Mark Gluck and Stephen Hanson.
