Areas of Research
  • Speaker Recognition
    Developed a number of successful techniques for large population speaker recognition in addition to general research and development in the field of pattern recognition with applications to Speaker Recognition (Large-Scale Identificaton and Verfication), Segmentation, hybrid systems with face recognition and text processing, large scale search techniques, etc. Active in this field at the present.

  • Optimization
    Applications of Optimization in very large Portfolio Optimization problems, Learning Control, Adaptive Control, Neural Network Learning. Very active in this field at the present including Research done in conjunction with the Research department of Merrill-Lynch.

  • Adaptive Learning Control
    Formulated for the first time the adaptive-learning control strategies and provided solutions based on Optimization Methods, Adaptive Ideas and new parameter estimation schemes. Also formulated a continuous adaptive learning control system with a quite strong and theoretically sound control strategy based on my previous work on adaptive parameter estimation and optimization. Active in this field at the present.

  • Signature Recognition
    Have done quite a lot of work in this field including signature compression and recognition (identificatin and verification). Active in this field at the present.

  • Speech Recognition
    Extensive participation in the research connected with the IBM ViaVoice product. Research areas include all aspects of Large-Vocabulray speech recognitoin, speech segmentation, and Small-Vocabulary systems.

  • Handwriting Recognition
    Over 6 years of research in large-vocabulary, unconstrained handwriting recognition. Extensive work on Feature Extraction, Language Modeling, Compression, Segmentation and Normalization leading to a fully operational system. Presently, active in this area.

  • Information Theory and Language Modeling
    Extensive research in Language Modeling and Information Theory pertaining to usage with Text Processing, Handwriting Recognition, Speech Recognition, and Hybrid Search systems using Textual Language as well as Speaker Voice and Face information.

  • Neural Network Learning
    Break-throughs in highly efficient learning schemes using second order techniques in optimization for Feed-Forward Neural Network Systems. Serveral journal and conference papers in this field including IEEE Best Paper Award for two conference papers in the field.

  • Electronic Music
    Treatment of Online Common Music Notation using a Pen as evidenced by An IBM Adventurous Systems and Software Research (ASSR) project granted for two years

  • Language Modeling
    Treatment of highly compressed dictionaries, statistical N-Grams, Template Language models and Decision-Tree-based Language Models

  • Image Compression
    Created Loss-Less Image Compression schemes or storing highly prized Art Collections of the Library of Congress.

  • Kinematics
    Generalization work on the Kinematic Analysis of General 4-Bar linkages (Planar, Spherical, and Skew). The generalization work resulted in a nuified analysis formula which applies to all types 4-Bar linkages.

  • Fluid Mechanics
    Research on Zero Gravity Fluid Behavior in conjunction with the NASA SPACE-LAB project. Experiments were carried out by the Space-Lab.
