  • Senior Software Developer IV

    Microsoft | June 2005 - February 2010

    • Developed web-content classification program, extending the technique used in anti-spam engine. As its ancestor, my program used Support Vector Machines (SVM) technique to separate samples in high-dimensional space and Bayesian estimations of conditional probabilities (Visual C++, C#, STL, WinForms, .NET). To recognize multiple categories with binary classification method like SVM, predefined categories were automatically organized into a binary decision tree. • Proposed geometrical and statistical methods of classifying domain names, representing them with character-based n-grams (patents #20090043721 and #20090043720). • Created prototype of pattern-discovery program, revealing highly decisive non-trivial patterns (containing no obvious keywords). • Performed benchmark analysis of three main text-extraction technologies, beneficial for keyword filtering in Forefront Server Security (FSS) product. • Recommended appropriate way of loading IFilters from memory streams, implemented later in generic FSS text extraction engine.
