Vasant Honavar's research and teaching interests span a number of areas including:


Research Overview and Selected Publications

Following is a brief overview of current research projects in Honavar's laboratory along with a few representative publications which provide more detailed information. A more complete list of publications can be found here. This research has been partially supported through grants from the National Science Foundation, the John Deere Foundation, and Iowa State University as well as research fellowships from IBM Corporation and the Iowa State University Graduate College.

Constructive Neural Network Learning Algorithms for Pattern Classification: Honavar's current research on neural network learning algorithms focuses on theory, design and experimental study of a family of efficient and provably convergent algorithms for incremental construction of neural networks for pattern classification and related machine learning applications. Constructive algorithms obviate the need for a-priori and often ad-hoc choices of network architectures. They can potentially yield near minimal networks whose size and complexity are commensurate with the complexity of the pattern recognition task (implicitly specified by the given dataset). In this context, inductive bias, incorporation of prior knowledge, cumulative multi-task learning are among the topics that are currently being explored. Related work explores automated feature subset selection and feature construction algorithms.

Intelligent Agents, Mobile Agents, and Multi-Agent Systems: Intelligent agents, mobile agents, and multi-agent systems offer a particularly attractive approach for the design and implementation of complex, flexible, and scalable information systems. Honavar's current research in this area focuses on the principles, design, and implementation of distributed knowledge networks (DKN) for information retrieval, information extraction, data-driven knowledge discovery, data and knowledge organization and assimilation, distributed problemsolving and decision support. Applications of DKN are bein explored in organizational decision support, bioinformatics, adaptive self-managing communication networks, intrusion detection, and distributed design and manufacturing.

Data Mining and Knowledge Discovery: Honavar's current research on data mining and knowledge discovery focuses on the design and implementation of tools for large scale automated data extraction (using text processing, image processing, speech recognition, information retrieval tools), knowledge acquisition and discovery (using machine learning) from heterogeneous (e.g., dictionaries, books, web pages, images, relational and object-oriented databases, bibliographic databases, etc.), distributed data sources. As part of this project, a modular and extensible toolkit of machine learning algorithms (KADLab) is being implemented.

Bioinformatics and Computational Molecular Biology: Biological data (e.g., genetic and molecular data, ecological data, botanical data, zoological data) is being accumulated and stored in digital form at astronomical rates. There is a growing need for intelligent data analysis tools for automated knowledge acquisition and discovery from such data sources. Honavar's current research is aimed at the design, implementation, adaptation, and application of a broad range of machine learning tools for data analysis and knowledge discovery in biological and agricultural sciences. Much of this research is being conducted in collaboration with biologists who are experts in various domains of interest.

Evolutionary Robotics and Artificial Life: Evolutionary algorithms (genetic algorithms, evolution strategies, genetic programming, evolutionary programming) offer an attractive paradigm for automated synthesis of sensory, behavior, and control structures for robots and intelligent agents. Honavar's current research in this area is focused on automated synthesis of neural networks, finite automata, and computational architectures for reactive and deliberative behavior in intelligent autonomous agents and robots under a variety of cost, performance, and environmental constraints. Related research explores evolution of communication, cooperation, and language in communities of intelligent agents.

Automata Induction, Grammar Inference, and Language Acquisition: Automata induction, the task of infering an unknown grammar (or equivalently, the corresponding recognition device) from examples finds applications in several areas including structural pattern recognition, language learning, information retrieval and computational biology. Honavar's research on grammar inference explores the design and analysis of algorithms for induction of regular grammars within different models of interaction between the learner and the environment. Of particular interest are models of language learning from simple examples, induction of large regular grammars, tree grammars and attributed grammars as well as acquisition of semantics along with syntax.

Spatial and Temporal Knowledge Representation and Inference: Honavar's research on knowledge representation focuses on techniques for representation of, and reasoning with, spatial and temporal knowledge under uncertainty, and their applications in robotics (e.g., acquisition and use of spatial maps for navigation), distributed multi-agent problem solving (e.g., utility-theoretic approaches to heuristic routing in large communication networks), and multi-agent systems.

Massively Parallel Architectures for Knowledge Representation and Inference: Artificial neural networks, because of their massive parallelism and potential for fault tolerance provide an attractive paradigm for the implementation of high performance computer systems for knowledge representation and inference for real-time applications. Honavar's research on neural architectures for knowledge representation and reasoning focuses on fault-tolerant neural network architectures for associative memories, data storage and retrieval, syntax analysis, and deductive inference.

Computational Models of Learning, Memory, and Behavior: Honavar's laboratory is involved in interdisciplinary research on learning and memory, with particular emphasis on design and theoretical and experimental analysis of and computational models of cognitive phenomena. This often leads to design and implementation of biologically inspired computational architectures for intelligence for applications in robotics and intelligent agents. Of particular interest are spatial learning and navigation in animals and computational investigation of the role of neuron-glia, glia-neuron, and glia-glia interactions in learning and memory.

Applied Artificial Intelligence: Honavar's laboratory works on various topics in applied artificial intelligence including pattern recognition, modelling, prediction, optimization and control problems in bioinformatics, protein structure prediction, computational genomics, robotics, image analysis, power systems, manufacturing systems, engineering design, diagnosis, computer security, communication systems, finance, and medical informatics. This work employs a broad range of artificial intelligence tools including knowledge-based systems, artificial neural networks, statistical pattern recognition, evolutionary computing, machine learning, and intelligent agents. Some of this research is carried out in collaboration with industrial partners.

Other Topics of Current Interest: Other topics of interest include: Computational Models of Discovery; Computational Models of Creativity; Computational Modeling and Simulation of Complex Systems (evolution, social systems, immune systems, communication networks, etc.); Hybrid Intelligent Systems; Philosophy of Mind; Intelligent Design and Manufacturing Systems; Applications of information theory and complexity theory (in particular, Kolmogorov complexity, minimum description length, and related topics) in computational learning theory and biology.
