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.
