Overview of Publications and Research Interests
I currently have over 405 publications, which include book chapters, and refereed publications which have appeared (or will appear) as either journal or conference papers. They reflect the results that I have obtained in the various areas that I have worked in, and with those whom I have collaborated over the years.

To see the entire list of my publications, and the list of news items (in the corresponding media) where I have been featured, click here.

Research Interests
My research interests span the areas of
Learning Systems, Data Retrieval and Storage, Statistical Pattern Recognition, Syntatical Pattern Recognition, Robotics, Adaptive Data Structures, Artificial Neural Networks, Query Optimization in Database Systems and Data Compression. Click on any of these for a catalogue of the results obtained in that area.

Recognition and Awards
I am a FELLOW of the IEEE as of January 2003 for contributions to "to automata learning and syntactic pattern recognition". Only a maximum of 0.1% of the voting membership of the IEEE is promoted to the Fellow rank annually. For a write up about this in the local newspaper please click here.

I am a FELLOW of the IAPR - the International Association of Pattern Recognition as of August 2006 for contributions to "fundamentals and applied problems in syntactic and statistical pattern recognition". A copy of the certificate is here. For a write up about this as a Carleton News Release please click here, here for a write-up from the Ontario Ministry of Research and Innovation, and here for a letter of appreciation from the Premier of Ontario. This was also highlighted in a local newspaper, as seen here. From the IAPR records, it seems as if (prior to 2006) I am the first ever IAPR Fellow in Ottawa, the first ever in Ontario, and the fifth ever in all of Canada to receive this honour. Also, only a maximum of 0.25% of the membership of the IAPR is promoted to the Fellow rank biannually. A write-up about this in a Norwegian University web-site is found here.

My paper titled "Using the Theory of Regular Functions to Formally Prove the Epsilon-Optimality of Discretized Pursuit Learning Algorithms" (with Ms. Zhang, Dr. Granmo and Dr. Jiao) was awarded the Best Paper Award for the 2014 International Conference on Industrial and Engineering Applications of Artificial Intelligence and Expert Systems held in Kaohsiung, Taiwan, in June 2014. A copy of the certificate is here, and a picture of me being awarded with the certificate is here.

My paper titled "On Using Adaptive Binary Search Trees to Enhance Self Organizing Maps" (with Mr. Astudillo) was awarded the Best Paper Award for the 2009 Australasian Joint Conference on Artificial Intelligence held in Melbourne, Australia, in December 2009. A copy of the certificate is here, and a picture of my student, Mr. Astudillo, and me with the award is here.

My paper titled "A Hierarchy of Twofold Resource Allocation Automata Supporting Optimal Sampling" (with Dr. Granmo) was awarded the Best Paper Award for the 2009 International Conference on Industrial and Engineering Applications of Artificial Intelligence and Expert Systems held in Tainan, Taiwan, in June 2009. A copy of the certificate is here, and a picture of my colleague, Dr. Granmo, and me with the award is here.

My paper titled "Modeling and Simulating a Disease Outbreak by Learning a Contagion Parameter-based Model" (with Dr. Calitoiu) was awarded the Best Paper Award for the 2008 International Conference on Health Sciences Simulation held in Ottawa, Canada, in April 2008. A copy of the certificate is here, and a picture of my student, Dr. Calitoiu, and me receiving the award is here. The Carleton News Releases are found here and here.

My paper titled "Self-adjusting of Ternary Search Tries using Conditional Rotations and Randomizing Heuristics" (with Dr. Badr) was cited as being Most Meritorious and was a winner of one of the Wilkes Best Paper Awards in 2006, by the journal The Computer Journal. The Computer Journal is the flagship journal of the British Computer Society.

In July 2006 Carleton University bestowed on me the honorary rank of Chancellor's Professor. This is a lifetime award bestowed by the University to a select set of senior professors who have excelled in research. The Carleton News Release is found here.

I have been awarded the Carleton University School of Computer Science Scholarly Achievement Award numerous times, and a Carleton University Research Achievement Award in December 1995, December 2001 and December 2007. For a write up about the latest award in the Carleton media click here.

My paper on "Stochastic Generalized Pursuit Learning Algorithms" (with Ms. Agache) was nominated for the Best Paper of the Year Award in 2003, by the journal IEEE Transactions on Systems, Man and Cybernetics .

My paper on "Optimal and Information Theoretic Syntactic Pattern Recognition" (with Dr. Kashyap) was awarded the Honorable Mention of the Year Paper Award in 1998, by the journal Pattern Recognition .

I have supervised almost 60 graduate (Masters and Doctoral) students, and this includes the ones I am currently supervising. 9 of these students have won University or Senate medals for their outstanding research - as demonstrated by their theses.

I was the Electrical Engineering Gold Medal Winner for the year 1977, at the Indian Institute of Science, Bangalore, India, for being the best graduating student.

I was the Kaloori Medal Winner for the year 1974, at the Indian Institute of Technology, Madras, India. I won the Siemens-India Medal for the year 1975, from the Indian Institute of Technology, Madras, India, for being the best graduating student from the Department of Electrical Engineering.
