ISBN 0-12-228630-8

Goals and Target Audience

Computational Intelligence PC Tools is targeted for senior undergraduate and first-year graduate students in engineering and computer science. It is also written for engineers, computer scientists, and others who want to learn about computational intelligence and its practical applications. At the end of most chapters, exercises are presented that test the understanding of the material presented, and that give the opportunity to expand knowledge of computational intelligence tools beyond the chapter conte nts. Executable code for major paradigm implementations is provided on a diskette with the book. Source code (written in C/C++) and additional executable code is available from the authors.

Introduction

Presents the goals and objectives of the text, and describes its intended audience. Presents an outline of the book, with a brief description of each part, chapter and appendix. Discusses use of the text in a course.

Chapter 1: Background

Discusses background of neural networks, fuzzy logic and evolutionary computation, and how they form the basis for the unified field called computational intelligence (CI).

Chapter 2: History

Reviews history of CI component technologies, and how they have been combined to form computational intelligence. The focus is on people, rather than just on theory or technology.

Chapter 3: Neural Network Theory and Paradigms

Reviews the concepts associated with neural networks. Included are terminology and symbology, and discussions of the three features of any neural network: architecture, processing element transfer functions, and learning algorithms. A number of network paradigms are discussed and compared. Preprocessing and postprocessing are examined.

Chapter 4: Neural Network Implementations

Presents implementations of back-propagation, learning vector quantization, and radial basis function networks. (Software is on the diskette.)

Chapter 5: Evolutionary Computation Theory and Paradigms

Reviews the four basic methodologies of evolutionary computation. Included are genetic algorithms, evolutionary programming, evolution strategies and genetic programming.

Chapter 6: Evolutionary Computation Implementations

Includes implementations of a Genesis-like genetic algorithm and a particle swarm optimizer. (Software is on the diskette.)

Chapter 7: Fuzzy Logic Theory and Paradigms

Discusses fuzzy reasoning, the basics of fuzzy set theory, and fuzzy membership functions. Presents examples of fuzzy reasoning systems using both Mamdani and Takagi-Sugeno methods. Examines measures of fuzziness.

Chapter 8: Fuzzy Logic Implementation

Presents an implementation of a fuzzy expert system. The implementation has both linear and nonlinear membership functions, and various fuzzification and defuzzification techniques. (Software is on the diskette.)

Chapter 9: Computational Intelligence Theory and Concepts

Discusses unified field of computational intelligence. Offers definitions. Discusses computational intelligence in context with other intelligence types. Compares adaptation with learning, and stochasticity with chaos.

Chapter 10: Computational Intelligence Implementations

Presents an implementation of a fuzzy min-max neural network. Also included is an evolutionary fuzzy expert system. (Software is on the diskette.)

Chapter 11: Performance Metrics

Examines issues related to measuring how well a CI implementation is performing. Performance measures discussed include percent correct, average sum-squared error, normalized error, evolutionary algorithm effectiveness measures, receiver operating characteristic curves measurements, confusion matrices, cost functions, and chi-square goodness-of-fit.

Chapter 12: Analysis and Explanation

Presents analysis and explanation tools that are used to explain how CI systems do what they do. Included are sensitivity analysis, Hinton diagrams, and explanation facilities. Application of CI tools to explanation facilities is reviewed.

Chapter 13: Case Study Summaries

Several case studies are summarized in this chapter. Each summary cites references where more information can be obtained, and discusses what makes the case study significant. Included are summaries describing electroencephalogram (EEG) spike detection, battery state of charge determination, schedule optimization, and control system design.

Glossary

Presents a comprehensive glossary of terms relevant to neural networks, evolutionary computing, and fuzzy logic.

References

A unified reference list for the book, comprising over 230 entries.

Appendices

APPENDIX A - This appendix briefly describes the Computational Intelligence Toolkit (CIT) software, which includes PC-executable code for all paradigms to which an entire chapter was devoted. Also included on the diskette is a User's Manual for all the software. The source code for this software, written in C/C++ is available on diskette from the authors for a modest price (less than $100). Included in this appendix (and on the diskette as an ASCII text file) is a one-page order form.

APPENDIX B - This appendix reviews additional resources that can be used to continue learning about computational intelligence. Included are the major technical societies around the world, the major journals, and a sampling of data bases and computer bulletin boards.

Software Diskette

A diskette in the back of the book contains software for all of the implementations discussed in the book. Executable programs and data files are included. An ASCII file containing an order form for the C/C++ source code is also included.
