From its humble beginnings in 1922 in infinite valued logics (ie uncertainty), fuzzy logic has grown exponentially both in theory and practice, and in applications as far flung as disc brakes, DNA sequencing, high speed trains, medical devices, musical synthesizers, camera apertures, star measurements, text mining, data mining, seismology, oceanography, biotechnology, web searches, aileron control, smart phone pen scripts, and much more.
The subtle idea of Fuzzy Logic (FL) is that in uncertain or limited data (or too much data) conditions, POSSIBILITIES as well as probabilities can exist between 0 and 1, not just as stochastic weights, but actionable fractional values within algorithms and circuits, as meaningful and practical measurements and formulas. This valuable text is a great triple threat volume-- equally relevant for self study, courses, and professional reference. It has been extensively revised to include almost a total rewrite of the 1995 to present state of the art.
There are numerous other texts that are very good, but either incomplete or much too detailed and technical in one narrow area, and thus more appropriate for graduate research in specifically chosen areas, including theory. This text is robust in theory with just the right level of abstraction, but is really for both the practicing and student engineer, and leaves off just perfectly where the grad texts take off.
Some background in statistics, truth values and regular logic, mathematical logic, computational complexity, programming and related areas is helpful, but not required. The author does a great job of laying the foundation before moving into advanced applications, and you really can begin at a basic intelligent undergrad level and follow it upward.
There are very new areas like ecorithms that aren't covered, but you can mine the references or a seminal volume like Valiant (Probably Approximately Correct: Nature's Algorithms for Learning and Prospering in a Complex World) to fill in those details. As an engineer and a patent reviewer at payroy dot com, I am seeing numerous new filings using many new twists on FL-- so an additional audience for this fine volume is inventors in addition to researchers, students, engineers, circuit designers, etc.
Even game programmers are finding applications, which I think I can say without giving too much away! The most important point is that there really is no other alternative to this fine volume in thoroughness, quality and depth if you want to either learn, or apply FL in more depth. Highly recommended. Of the approximately 13 texts that are candidates for library purchases in our database in this area, this is #1.
CODE: As of this 2013 writing, the MATLAB web code on Wiley for this volume is still active-- very valuable indeed. If you buy the text used, you do NOT require any one time use codes that might be missing from the used text to access the extra features. Just be sure you get the 3rd edition if you do buy from Amazon warehouse or another Amazon third party used! The 1995 edition is way out of date today.
Library Picks reviews only for the benefit of Amazon shoppers and has nothing to do with Amazon, the authors, manufacturers or publishers of the items we review. We always buy the items we review for the sake of objectivity, and although we search for gems, are not shy about trashing an item if it's a waste of time or money for Amazon shoppers. If the reviewer identifies herself, her job or her field, it is only as a point of reference to help you gauge the background and any biases.
